If your Mac is suddenly feeling very sluggish and unresponsive, it’s possible that a runaway application is consuming a large percentage of your CPU’s processing power. To find out, we’ll use a built-in macOS utility called Activity Monitor. Here’s how.

First, open “Spotlight” by pressing Command+Space or by clicking the “small magnifying glass” icon in your menu bar.

When the “Spotlight Search” bar pops up on your screen, type “activity monitor” and hit “Return.” Or you can click the “Activity Monitor.app” icon that appears.

In “Activity Monitor,” you will see a list of all the processes running on your computer. The term “process” is a generic term for any program running on your Mac. This includes both applications you run and silent programs operating in the background that make your computer work properly.

To see which process is using the most CPU, click the “CPU” tab. Then click the “% CPU” column header until the carat beside it is facing downward. This will rank the processes, from greatest to least, by what percentage of the total CPU processing capacity they are using.

Look for suspiciously high numbers in the “% CPU” column beside one of the entries in the list. Most applications rarely use over 50% CPU unless they are doing something very processor intensive, such as playing a complex game or rendering a video, and you will usually understand why. In that case, it’s best to just wait until the task completes.

But if a runaway process is your issue—a program that gets stuck in an unwanted CPU-intensive loop—it should be obvious by looking at the high CPU % listed in Activity Monitor. When you get into the 90% range or above, the odds are high that that process will dramatically slow down your machine.

At this point, if the process using a large percentage of the CPU is an app, you can try to quit it using the usual methods, such as selecting “Quit” in the File menu or right-clicking its icon in the Dock and selecting “Quit.”

But if the process or app is unresponsive and you would like to force it to close, click the process in the list to select it, then press the “Stop” button, which looks like an octagon with an “X” inside.

Upon pushing the “Stop” button, a small menu will pop up asking for confirmation. Click “Force Quit.”

After that, the problematic app or process will close. If your computer becomes responsive again, then you know that an unresponsive runaway process was the issue.

If you keep having repeated CPU issues with the same app, it’s best to try to update the app, which may fix a bug that is causing the problem. You could also try updating macOS, which may fix a bug with a background process or a bug that is affecting how an app runs. It also never hurts to restart your Mac, which can solve a variety of problems. Good luck!

If you rely on a MacBook Pro as your business desktop replacement or mobile computing companion, you may want to keep an eye on your system’s CPU usage to diagnose a system slowdown or see which applications use the most processing power. Mac OS X ships with a utility you can use to monitor which applications and processes demand the most of your MacBook Pro’s CPU. Launch Activity Monitor to view your computer’s disk activity and usage, check your network traffic, examine system memory and see real-time stats on CPU usage.

Open your Applications folder and double-click on the “Utilities” subfolder to open it. Double-click on the icon for “Activity Monitor” to launch it.

Click on the “CPU” tab at the bottom of the Activity Monitor window to display processor-use stats and a live stacked-column activity graph. User processes belong to you and stem from the applications you launch or the processes they use. System processes belong to the computer itself. The “% Idle” statistic represents the amount of processor power that’s not in use at the time the utility polls the system. The activity graph’s red bands show how much processor power your computer claims for your operating system. In green, you’ll see the activity from applications you launch and other processes that belong to you as the current user. If your computer’s running processes claim your full processor power, the combined height of user and system bands reaches the top of the graph.

Set the drop-down menu at the top right of the Activity Monitor interface to “My Processes” to view only those that belong to your user ID. Switch to “All Processes” to see the full list of what’s running on your MacBook Pro.

Click on the name of a process to select it. Shift-click on another item in the list to select all the entries between your original selection and the second process name you select. Command-click on additional entries to add them to your selection individually. After you’ve made your selection, set the drop-down menu to “Selected Processes” to track only those items in the list of processes. Note that the statistics at the bottom of the window continue to reflect all the processes running on your system.

Click on the “CPU” header in the main portion of the Activity Monitor window to sort the list of processes by the amount of CPU capacity they use. When the arrow on the CPU header tab points down, the list sorts in descending order with the most active processes at the top. Click on the header a second time to change the sort order.

Your PC or Mac’s central processing unit (CPU) is like its brain. It’s the piece of your computer that tells every other part how to work, which programs to launch, which pictures to show, and more.

Your CPU usage — in simpler terms, how much of the CPU’s energy is being used — is measured with a percentage. When your computer is idle, your CPU usage should float around the single digits or low teens. When running videos, games, or other intensive applications, the CPU usage should jump, but still never stay at 100% for too long.

If you’ve noticed performance issues, like a slow startup time or lagging apps, you’ll want to check your computer’s current CPU usage. That way, you can make sure the CPU’s usage percentage is staying in a healthy range, both when your computer is idle and running at high gear.

How to check your CPU usage on a Windows PC

Using the Task Manager

1. Press Control + Alt + Delete on your keyboard.
2. On the screen that’s summoned, select “Task Manager” at the bottom.

At the top of the Task Manager, click “Performance.”

Quick tip: If you don’t see this option, your Task Manager might be in “Fewer details” view — click “More details” in the bottom-left to reveal all the options.

In this menu, click “CPU” in the left sidebar. You’ll see a graph showing your CPU usage over time, and you can find your current usage listed under “Utilization.”

Using the Resource Monitor app

Open the Resource Monitor app, which you can find by searching for it.

You’ll see your CPU usage near the top of the Resource Monitor, by the green box icon. An itemized breakdown of CPU usage by applications will be listed below.

How to check your CPU usage on a Mac

Using the Activity Monitor app

Open the “Activity Monitor” application. If the app isn’t in your Dock, you can find it by searching for it with Spotlight, or by going to your Applications folder and selecting “Utilities.”

Check this list to see which applications are using your CPU power, and how much each one is using.

Quick tip: If you don’t see the “% CPU” column, right-click on “Process Name” and select “% CPU.”

You can also look at the box at the bottom of the screen, which shows your CPU’s power split into three categories: “System,” “User,” and “Idle.” Adding the System and Idle percentages together will give you your total current CPU usage.

If you see any unnecessary apps gobbling up CPU usage, you can close them with the task manager.

Do you find yourself frequently starting at the spinning beach ball on your Mac — the moment when your apps slow down or grind to a halt?

If so, your Mac could be overtaxing its CPU with various simultaneous processes, which ultimately results in sluggish performance. Truth is, regardless of how powerful your Mac is, it only has so much CPU to allocate to everything you want to do, and sometimes it can hit its limits.

To make your Mac fast once again, you need to know how to check CPU usage on Mac and how to reduce CPU usage through quitting and optimizing various unnecessary processes.

But first, let’s define what CPU actually is.

What is CPU on Mac?

CPU (Central Processing Unit) is the core of any computing device, from your Mac to your iPhone or Apple Watch. Its job is to simply follow instructions it’s been given, which bundle together into processes.

An important metric of CPU productivity is CPU time (or processing time), which is measured by seconds your Mac’s CPU spends processing certain tasks. The longer any given task takes to complete the busier your system is and the more overloaded your CPU becomes.

If your Mac has high CPU usage, even the most simple tasks will become throttled and take a long time to be done. In other words, your performance will suffer significantly. Reaching 100% of CPU will essentially stall your Mac completely.

The good news is you can try to lower the CPU usage by detecting the underlying causes and monitoring all the active (and background) processes.

High CPU usage could be the sign of malware installed on your Mac and running various scripts. It could also mean that you’re trying to run too many tasks at once or you’re working in apps that are too intensive for your Mac. For example, exporting 4K video on an old MacBook Air through Final Cut Pro is probably not a great idea.

How to check CPU usage on Mac

Knowing which tasks or apps are consuming your CPU and slowing down your Mac could be challenging if you don’t know where to look.

Luckily, your Mac has a built-in utility to track all of its processes. It’s called Activity Monitor and can be accessed in the Applications (⌘ + Shift + A) ➙ Utility folder.

Launch Activity Monitor and make sure the filter up top is sorted by CPU usage. Now you’ll clearly see all the apps and processes that use the computing power of your Mac. At the bottom, you’ll see system as well as user processes summary and how much CPU is still available (idle).

To lower your Mac’s CPU usage, you can quit any process you recognize as unimportant.

Note: Don’t quit all processes at random, as some of them are essential to the proper functioning of your Mac.

If the process is taking more than 100% of your CPU, it might be an indication that this process is out of control (frozen) and needs a reset.

To quit any process in Activity Monitor, simply highlight it and then click the Stop icon in the top bar.

How to reduce CPU usage automatically

While Activity Monitor is a helpful utility, it’s quite bothersome to run it all the time. Instead, you should really use a few third-party apps that make the monitoring process much more seamless.

iStat Menus, for example, is a super powerful utility that lives right in your menu bar and can show you every detail about your Mac at a glance, from CPU and GPU load to RAM usage, temperature, disk health, battery cycles, and more.

You can customize iStat Menus to your specific needs and then just click its icon to see everything you need to know in real-time graphs and percentages. If something looks wrong, just launch Activity Monitor from iStat Menus in one click and quit the process in question.

Both iStat Menus and Activity Monitor make tracking processes on your Mac easy. But what if you can’t quit all the processes that are taking over your CPU? Is there a way to contain them?

App Tamer is a brilliant CPU manager for your Mac. Similarly to iStat Menus, it tracks all your Mac’s processes and makes them available in a visual dropdown right in your menu bar (although you can filter out essential system processes). It also shows you the CPU load right on your menu bar, without clicking anything.

What’s unique about App Tamer, however, is its ability to limit the CPU load of any given app. To do so:

1. Open App Tamer
2. Click on any active app
3. Check “Slow down this app if it uses more than”
4. Enter the appropriate CPU percentage

What to do with the WindowServer Mac process?

Monitoring your active processes over time, you’ll without doubt notice that a WindowServer Mac process is often taking up a considerable part of your CPU. But what is it? Can you quit it?

WindowServer is one of the system processes and what it does is draw all the elements on your screen, from app windows to icons. So the amount of CPU that WindowServer is consuming is directly correlated to the amount of open windows you have on your Mac.

You can’t stop the WindowServer Mac process completely, but you can definitely lower its CPU usage:

• Close all the windows and apps you don’t need
• Reduce Transparency in the System Preferences ➙ Accessibility ➙ Display menu
• Delete all the extra Desktops in Mission Control
• Restart your Mac

As you can see, learning how to lower CPU usage is fairly easy. But even following all the advice about, in rare cases, might not produce the desired result.

Some additional tips to reduce CPU load are connecting your laptop to a power source, as your Mac could run slower on battery power, and upgrading your hardware if you find that you’re regularly running into 100% CPU usage.

For most people, however, monitoring CPU usage with iStat Menus and limiting certain apps’ appetite with App Tamer should be more than enough.

Best of all, you can download iStat Menus and App Tamer absolutely free for seven days through the trial of Setapp, a platform with more than 210 top-rated Mac apps, from Disk Drill that recovers your hard drive in case of failure to Elmedia Player that handles any audio or video format with ease. Try every Setapp app today at no cost and see for yourself!

I would like to limit the amount of CPU time dedicated to certain processes (e.g. Firefox, Safari, . ).

I can’t understand why such programs, even when not used (nothing loading, no animations, running in the background, . ), are so resource hungry. Why must a browser eat 50% or more of my CPU? Can I limit it to 10%?

Its not exactly what you wanted, but, in regards of google drive and chrome this what did the trick for me:

Google Drive (“Backup and Sync”)

set back to normal:

Chrome

de-prioritize all current processes:

set back to normal all current processes:

cputhrottle is the tool you need. You can install it with Homebrew.

You can monitor a series of processes by name by running the Bash script below. I’m not quite sure how to turn this into a login item since cputhrottle requires superuser permissions. Run it as a script, in an Automator workflow, whatever:

I’ve added a different version for this script (a bash script), which might be useful for people looking for limiting the CPU for multiple applications.

This new script also allows you to specify a list containing the application name and the CPU limit for it.

The main difference is that you can add cpu limit per application, and it will run only once per application. I’ve also added the option for killing all cputhrottle processes.

The script assumes that both cputhrottle and pidof are installed before running it.

You can indeed! There’s CPUThrottle, which allows to specify a PID to restrict.

Note, they’re trying to use that much for a reason, it’s a useful tool but whether it’ll make it better or worse for you on a day to day will be something you discover.

Although not a direct answer to the OP’s question, if you’re having an issue with a particular process taking up too much of your CPU time, and making your computer unusable, and you don’t mind how long that process takes to finish the task it’s working on, you can use the renice to alter the priority of that process, making it behave nicely (hence the name).

First, you need to find the PID of the process that’s using up the CPU resources. You can either do that in Activity Monitor, or in Terminal.app with the ps command – e.g. to find the PID of the Safari browser, type:

The second line above is the output, and the PID is 17452 in this particular case.

Then, the next task is to change the priority of the process (let’s say it’s Safari we want to make behave nicely). To do this, in Terminal.app type:

The -n option changes the nice level by adding 10 to the current value (0 by default). The range of values are -20 to 20, with lowest value meaning highest priority. As an ordinary user, you can use values 0 to 20. To assign a negative value, you need to have root privileges (e.g. use sudo command). Read more about nice and renice by typing man nice and man renice in Terminal.app.

nice and renice don’t limit the percentage of the CPU available to a given application per se, they do however allow to change the scheduling priority, or in other words how much of the CPU time a process will get. This is all relative to the CPU load on your system, so if the system is under utilised, you most likely won’t see any difference.

If you’re looking for the source of lagging, slow opening, or other problems, or if you’re just curious about how your computer is running, there are easy ways to check system performance on a Mac.

Check Mac computer performance

The easiest way to check system performance on a Mac is to use the Activity Monitor, a built-in application that gives you a live overview of your Mac’s hard drive, RAM, processor, and network usage.

1. To access the Activity Monitor go to Finder, Applications, Utilities. Click Activity Monitor.
2. Choose the process category you’d like to check on. You can choose from CPU, Memory, Energy, Disk, Network, and Cache.
3. You can then choose how much information to display and in what format. For example:
   • All Processes
   • All Processes Hierarchically, this allows you to see parent/child relationships in processes
   • My Processes, processes owned by your macOS® user account
   • System Processes, processes owned by macOS
   • Other User Processes, processes not owned by the root user (administrator account) or the current user
   • Active Processes
   • Inactive Processes, processes that are sleeping
   • Windowed Processes, processes that create a window for user action, usually apps
   • Selected Processes, processes that you selected in the Activity Monitor window
   • Applications in the last 8 hours, apps that have run in the last 8 hours.

What to check

If you’re looking for a specific performance measure, you can find it, but there are some particular things to watch for.

Check the CPU on a Mac

You can sort the CPU pane by a variety of columns to see how much of the processor is being used by each application. This information can help identify processes that are affecting performance. The CPU Load graph shows the percent of capability currently being used. If the CPU Load is consistently over 60% you might want to check for hidden and background processes that are using a lot of processor space. Close or delete them if possible.

Check the Memory on a Mac

The Memory pane shows how memory is being used. The Memory Pressure graph illustrates the availability of memory. If the graph shows a lot of yellow and red, it might be time to increase the amount of RAM in your computer.

Check the Energy on a Mac

The Energy pane shows both overall energy use and the energy used by each open app. An important item to look for is apps that are preventing the computer from going to sleep in the Preventing Sleep column. If you are trying to save energy when the computer is not being used, be sure to shut down those apps that prevent sleep.

Check the Network on a Mac

The Network pane shows how much data the computer is sending or receiving, broken down by individual applications. If you’re monitoring how much data you’re using, this is a good place to observe which apps are using the most data.

Monitor performance

If you prefer to monitor performance in real time, you can monitor CPU usage in the background as you work in other applications.

To open a window, choose Window, then CPU Usage.

If you would like a graph of the information in the Dock, choose View, Dock Icon, and CPU Usage.

Conclusion

Apple® offers a suite of performance monitors in Activity Monitor. These monitors allow you to track, and potentially tweak, your computer’s performance.

Similarly to the Windows equivalent, in the Apple Task Manager you can easily closeprograms that are frozen or hanging. But if you want more details about a problem, you’ll need to open the Mac Activity Monitor. This lets you kill unused or unresponsive applications, and consult statistics on CPU and memory load, and energy use. But how do you open the Task Manager on a Mac? And what information is shown in the Activity Monitor? We’ve put together a step-by-step guide to help you out.

Force quitting programs using the Mac Task Manager

The Mac Task Manager is a mini-version of the Activity Monitor. To open it, simultaneously press down the [CMD] + [ALT] + [ESC] keys on your keyboard. This will open a window containing a list of all currently opened programs and applications that are running in the background. Select the program or application that has frozen and click on the “Force Quit” button to close it.

The Alt key is also referred to as the Option key. In fact, on some keyboards it is actually labelled “Option”.

List of programs in the Mac Task Manager

Mac Activity Monitor and CPU load

Like the Task Manager, the Mac Activity Monitor also lists all of the processes that are running on the system. You can open it by going into Applications and selecting Utilities, or searching for it directly in Spotlight by clicking on the magnifying glass in the upper-right corner of the menu bar.

The Mac Activity Monitor is split into several sections: CPU, Memory, Energy, Disk, Network, and (in later versions) Cache. The list of processes includes user apps, system apps used by the operating system, and invisible background processes. You can choose which columns to display and filter the processes by going into the “View” menu. As well as the Mac Activity Monitor, you can also install other programs such as htop to manage system processes.

CPU pane

The “CPU” pane shows how different processes are affecting CPU performance. Alongside the stats in the “Energy” pane, this information can help you work out what processes are affecting the performance, battery runtime, temperature and fan activity of your Mac. Just below the main window, you will see an additional section containing the following information:

• System: Percentage of CPU capability currently being used by system processes.
• User: Percentage of CPU capability currently being used by apps or processes launched by the user.
• Idle: Percentage of CPU capability not in use.
• CPU Load: Percentage of CPU capability currently being used by all processes (System and User combined).
• Threads: Total number of threads used across all processes.
• Processes: Total number of processes that are currently running.

When you open the Activity Monitor, you might notice that the CPU load for the kernel_task process is rather high, and also that the fan is working harder than usual. One of the roles of kernel_task is to regulate the temperature of the CPU.

Memory pane

The Memory pane of the Mac Activity Monitor tells you how memory is currently being used. The section at the bottom shows the following statistics:

• Memory Pressure: This is a graph that illustrates the availability of memory resources.
• Physical Memory: Total amount of RAM installed.
• Memory Used: Total amount of RAM currently in use.
• App Memory: Total amount of memory currently being used by apps and their processes.
• Wired Memory: Memory that cannot be compressed or paged out to the hard drive and that must therefore remain in RAM.
• Compressed: Amount of RAM that is compressed to make space for other processes.
• Swap Used: Space that the memory management system of the OS is using on your start-up drive.
• Cached Files: Memory that was recently used by apps but is now available to other apps.

Energy pane

The “Energy” pane provides information on overall energy use and tells you how much energy is being used by each app. As in the other views, you can click the column headings to sort the processes according to the values measured. The bottom pane shows the following:

• Energy Impact: Total energy used by all apps.
• Graphics Card: Type of graphics card installed.
• Remaining Charge: Percentage of battery charge remaining.
• Time Until Full: Amount of time the Mac must be plugged into the mains before it is fully charged.
• Time on AC: Time elapsed since the Mac was plugged in.
• Time Remaining: Estimated amount of time the Mac can keep running on battery.
• Time on Battery: Time elapsed since the Mac was unplugged.
• Battery (Last 12 hours): Battery charge level over the last 12 hours.

Something New

Zoom can be a bit of a resource hog. If you fear the video chat service is slowing down your PC, that’s something you can verify for yourself.

For a variety of reasons, it’s important to know what CPU usage is like for people running Zoom on Windows 10, macOS, and Chromebook. Any software that puts a strain on CPU performance creates issues for that specific program and other functions on an operating system. More importantly, there are reports that Zoom could be unusually taxing on people’s PC’s.

By most accounts, the bigger issues related to Zoom being a resource hog are related to its tertiary features. That’s a great thing because it means that by turning off a few bells and whistles, it may be possible to reduce CPU usage. These include features like the 16:9 ratio for video or the background noise suppression option. The latter of which is always a CPU-heavy operation in just about any program, so it’s even more resource-intensive with Zoom, a platform that also has multiple live video feeds streaming at once.

Before making any settings changes though, the first step is to gauge whether Zoom is eating up your resources. The process to get there will differ based on your operating system, but the goal is the same: if you find that Zoom uses more of your CPU than you’re comfortable with, turn off some features or close other applications to see if that corrects the problem. The ideal CPU usage percentage is, of course, subjective, but a good metric to go by is simply how well Zoom or other programs you’ll run alongside it perform. If things are significantly slower while Zoom is up – or if you notice a much larger drain on your battery or an uptick in fan noise – you know there’s an issue.

How to Monitor CPU Usage

Mac users have several ways to check out their CPU usage. The recommended way is to simply open the Activity Monitor app and give the chart a look. The default tab selected should be CPU but if that’s not where you land upon opening the app, just click there. One of the columns presented should be labeled “% CPU” and clicking it will sort your results to show which apps are putting your CPU to work the most, in ascending or descending order.

On a Chromebook, as with most system-related functions, you’ll need to open the Google Chrome browser. The menu icon (three dots stacked vertically in the top-right corner) should have an option labeled “More Tools”. Within that section, there will be a Task Manager. This screen will also allow sorting active processes by CPU usage, which’ll make it easier to notice if Zoom is doing a little bit too much.

For Windows 10 users, the process of checking CPU usage is just as simple. There are multiple ways to reach the operating system’s task manager, including right-clicking on the the taskbar and selecting it or pulling up the CTRL/ALT/DELETE menu. Once there, the list can again be sorted by the most CPU-demanding processes on the machine.

Speed Up Your Slow Mac

There are few things more frustrating than a computer that barely works. The rainbow “circle of death” is familiar to most Mac users, and usually elicits a groan and a sigh. You might bargain with yourself while watching it spin—and maybe it just needs a minute. Maybe it’s been a bit too long since you restarted your computer. Or maybe it’s just time for a new laptop.

If you multitask and like to have many apps running simultaneously, your device’s CPU (central processing unit) is probably working overtime. The CPU is the brain of your Mac, and sometimes it needs a break. Additionally, older Mac devices can start to slow down over time, and that’s likely because you’ve installed too many apps, games, or programs.

To make an old Mac feel fast and new, or just to speed things up, it’s important to know how to check CPU usage on Mac. More importantly, you’ll want to know how to lower CPU usage by filtering out unnecessary programs and optimizing the operating system.

A set of tools from Setapp could help you sort this out and get things running a bit faster.

What is Mac CPU and How Does It Work?

The CPU is the main chip inside your computer, phone, and even some cars that is responsible for performing most system tasks. It follows instructions given by the user, apps, and programs. For example, when hardware or software gives commands, the CPU connects these tasks to appropriate components on the system and peripherals like displaying video signals on your monitor.

Processing time, or the speed at which your Mac does what you ask it to, changes based on how overloaded the system is. Some tasks are more resource-intensive than others. For example, if you’re trying to encode a 4K video, download files, have dozens of web browser tabs open, and try to have a Zoom call at the same time, the system might slow down and struggle.

If your Mac has high CPU usage, even the smallest of additional tasks, like opening Apple Music, will probably take a long time, and overall performance will suffer.

Thankfully, it’s possible to lower your device’s CPU usage by uninstalling apps you no longer use, looking for and detecting underlying problems—like malware—or simply monitoring your CPU usage for issues and slowdown.

How to Check CPU Usage on Your Mac

Conveniently, Apple includes a tool called the Activity Monitor, which is accessible from the desktop in the Applications folder. This tool will display everything that’s currently running on your computer.

You could also press (⌘ + Shift + A) and open the Utilities folder, then the Activity Monitor.

You’ll see all the processes, programs, and apps using your Mac’s processing power from here. At the bottom of the window, you’ll see how much of the CPU is being used or sitting idle. In this area, you can lower your Mac’s CPU usage by quitting programs that don’t need to be running.

Note: Some functions are required for your Mac to operate.

Reduce CPU Usage With iStat Menus

Digging through the Activity Monitor isn’t ideal for the average user, which is why we recommend a third-party app instead. These apps make the monitoring process automatic and simpler.

iStat Menus, from Setapp, is a powerful tool that does all the heavy lifting for you. It sits up on the top right side of your Mac’s menu bar and will show you critical information about your Mac. That information includes the CPU usage, GPU load during gaming or video encoding, RAM usage, and even information like the temperature of your device, overall computer health, and battery recharge cycles on MacBooks.

It’s a powerful tool that gives you more insight into your machine, habits, and if anything is potentially problematic behind the scenes. You can even customize the entire iStat Menu to show only what you want to see instead of everything we mentioned above.

If you notice something wrong, simply launch the Activity Monitor from the iStat Menus and quit whatever is slowing down your machine.

Limit Hidden Start-Up Tasks

Another thing you can do is manage all the auto-run programs that automatically start running the moment you turn on your computer. Every time you turn on your Mac, these auto-run programs begin while your operating system is also still starting up.

Once your computer boots up, auto-run programs are always running on your machine. While this might make it faster to open and use them day in and day out, many auto-run applications are unnecessary and can clog up your CPU allocation. Once you manage some of those auto-run programs, your Mac will likely boot up faster, run faster, and have more CPU power to do the things you want.

Manage Your CPU With App Tamer

Another program from Setapp, called App Tamer, is a tool designed to track everything running on your device to help ensure improved performance. App Tamer shows processes similar to iStat Menus, but you can take it a step further and prioritize CPU power for specific apps.

1. Open App Tamer.

2. Click on any active app.

3. Check “Slow down this app if it uses more than.”

4. Enter the appropriate CPU percentage.

If a certain app happens to occupy all of your CPU’s processing power, you can set limits on that specific app. In other words, App Tamer will let you prioritize which apps on your Mac receive power from the CPU, and less important apps will slow down or wait until more CPU power becomes available.

Something’s clearly not right. Maybe your Mac has slowed to a crawl with frequent spinning beachballs and a juddery interface. You reach for Activity Monitor, and at the top of the list of processes in the CPU view there’s a process stealing 100% or even more. What do you do next? Select that process and click on the Stop button? This article explains.

The first problem you may need to grapple with is that percentage. If you thought that meant something out of hundred, then suspend your rational thought for a moment, as Apple uses it to refer to CPU “capability”. On any system with more than one core, this seems to represent the total across all available cores, and thus can readily exceed 100%. My iMac Pro has managed just over 1,000% on occasion.

Next, look carefully at the process which is hogging that high percentage. Is it an app displayed with its icon and you as its user, an app helper or similar, or part of macOS? If you don’t recognise it with confidence, tread carefully as there are some pitfalls with processes which are special. Many have giveaway names which relate them to apps and services, such as anything containing the letters Safari. Note the following in particular:

• cfprefsd , which is responsible for managing preference settings across most apps.
• distnoted , which is a background service handling distributed notification for many processes.
• kernel_task , which always has a PID of 0. This is the kernel, which busies itself to block other processes when your Mac is getting hot, and is discussed more below.
• launchd , which always has a PID of 1. This is the master launcher of other processes, second in importance to the kernel itself.
• logd , which is the unified log housekeeper, and essential for keeping your logs up to date and maintained.
• mdworker and mdworker_shared processes, which are multiple. These are the macOS metadata services which compile and maintain Spotlight indexes, and are discussed more below.
• WindowServer , which should have a PID of around 332, but varies with macOS version and configuration. This is WindowServer, responsible for compositing individual windows into the display image, and routing events such as clicks/taps to the correct app. Without it, there’s no GUI and no control over it, and it’s discussed more below.

If the process with the high CPU percentage is one of your currently running apps, and it appears to have become unresponsive, then rather than using the Stop button here, press Command-Option-Escape to see the Force Quit dialog, select it there, and force it to quit. This should ensure that all related processes are also shut down properly. Bear in mind that seizing the CPU in this way might actually be correct behaviour if you’ve given that app something computationally intensive to do.

Most services provided by macOS will be relaunched automatically if you decide to Stop them. However, that might not solve the problem, as that process may already be crashing repeatedly and being restarted. If you’ve done nothing to address the underlying problem of why they’re taking so much CPU, you may find that they soon return to the same state. Activity Monitor provides good tools for exploring what’s going on in more detail: check how much memory that process is using, whether it’s also using the GPU heavily, how many threads it has, and so on. Many of these are available using the Inspect button.

You can also get a much better idea of what’s going on by looking at the log. This is one of the few times that you could justifiably use Console rather than Ulbow or Consolation, as its live stream can give you a good idea of what the busy process is writing to the log. For example, mdworker and mdworker_shared processes can choke over indexing specific files or other metadata tasks, and may be reporting that error hundreds of times each second in the log. If you can identify the file which is causing that problem, you may be able to remove it and let the processes get back on with their work.

Although WindowServer is seldom a major CPU hog, when it is, it’s difficult to know what to do. If you’ve still got control of your Mac, try shutting down apps and any screen-sharing which might be exerting too heavy demand on it. You might be able to log out and log back in again to clear the problem, but restarting may be the only solution.

If it’s kernel_task , there are several potential causes, including:

• the kernel is overloaded, and liable to panic;
• the kernel is blocking other runaway processes as part of your Mac’s strategy to control internal temperature;
• there’s a faulty temperature sensor in your Mac, which is misleading its temperature control system into believing that it’s overheating, which is causing kernel_task to try to block other processes and allow the CPU to stay cool;
• the kernel is just heavily loaded at present, and will return to normal in due course.

Distinguishing these isn’t easy, and the last thing you want to do is interfere with your Mac’s normal response to rising internal temperatures. However, if it has only just started up, that should make you suspect other causes.

When you’ve coped with the immediate problem, consider what you can do to prevent it from occurring again. Some high CPU loads can result from incorrect permissions in your

/Library folder: this is particularly true of those with Safari in their name. Check the list of symptoms given here. At present, Apple has removed its article detailing this and its recommended solution, suggesting that doesn’t work after all.

If you’re left unsure as to what happened, make a detailed note of the circumstances in which this occurred. If it happens again, you’ll then be in a much better position to reach a diagnosis, or at least point a finger. Be careful, though, when searching on the Internet for solutions: many only apply to older versions of macOS, or may be ill-informed.

I wish you success!

Thanks to John for pointing out the current variability in the PID of WindowServer. It once used to be a sentinel PID.

If your Mac is suddenly feeling very sluggish and unresponsive, it’s possible that a runaway application is consuming a large percentage of your CPU’s processing power. To find out, we’ll use a built-in macOS utility called Activity Monitor. Here’s how.

First, open “Spotlight” by pressing Command+Space or by clicking the “small magnifying glass” icon in your menu bar.

When the “Spotlight Search” bar pops up on your screen, type “activity monitor” and hit “Return.” Or you can click the “Activity Monitor.app” icon that appears.

In “Activity Monitor,” you will see a list of all the processes running on your computer. The term “process” is a generic term for any program running on your Mac. This includes both applications you run and silent programs operating in the background that make your computer work properly.

To see which process is using the most CPU, click the “CPU” tab. Then click the “% CPU” column header until the carat beside it is facing downward. This will rank the processes, from greatest to least, by what percentage of the total CPU processing capacity they are using.

Look for suspiciously high numbers in the “% CPU” column beside one of the entries in the list. Most applications rarely use over 50% CPU unless they are doing something very processor intensive, such as playing a complex game or rendering a video, and you will usually understand why. In that case, it’s best to just wait until the task completes.

But if a runaway process is your issue—a program that gets stuck in an unwanted CPU-intensive loop—it should be obvious by looking at the high CPU % listed in Activity Monitor. When you get into the 90% range or above, the odds are high that that process will dramatically slow down your machine.

At this point, if the process using a large percentage of the CPU is an app, you can try to quit it using the usual methods, such as selecting “Quit” in the File menu or right-clicking its icon in the Dock and selecting “Quit.”

But if the process or app is unresponsive and you would like to force it to close, click the process in the list to select it, then press the “Stop” button, which looks like an octagon with an “X” inside.

Upon pushing the “Stop” button, a small menu will pop up asking for confirmation. Click “Force Quit.”

After that, the problematic app or process will close. If your computer becomes responsive again, then you know that an unresponsive runaway process was the issue.

If you keep having repeated CPU issues with the same app, it’s best to try to update the app, which may fix a bug that is causing the problem. You could also try updating macOS, which may fix a bug with a background process or a bug that is affecting how an app runs. It also never hurts to restart your Mac, which can solve a variety of problems. Good luck!

In this article, we explain how to check CPU usage on Mac.

What is CPU and how does it work

CPU (Central Processing Unit) is the main chip inside computers, which is responsible for performing all system tasks. In short, the CPU is called the brain of the computer as it gives commands to all parts of the system, following the instructions given by programs running on a computer. For example, when hardware or software gives commands, the CPU connects these tasks to appropriate components on the system and peripherals like the keyboard or mouse.

What are the different types of CPU

When it comes to understanding types of CPU, these criteria should be taken into account:

• The number of cores (CPU with 1, 2, 4, 8 or more cores).
• The usage (for servers, desktop or mobile).
• Architecture (32 and 64 bits, or other types).
• Vendor (Intel, AMD)
• Operating frequence and additional criteria.

Thus there are different types of CPU depending on the criteria above.

How much CPU usage is normal

The CPU usage continuously varies based on running activities on your computer. There is definitely no specific CPU usage that your computer should have. Even if the CPU usage is around 100%, this means that your computer is trying to do more work than it has the capacity for. You should worry about CPU percentage only in the event you face slow Mac performance.

Read on to learn how to check CPU usage and fix a slow Mac.

How to view CPU usage on Mac

To check CPU usage on Mac, use the default Apple utility Activity Monitor. Activity Monitor is a Mac performance monitor that shows what programs are running and how many resources they are using.

Run Activity Monitor from the launchpad or from the Applications folder.

How to use CPU information to optimize Mac’s performance

Based on the results of your Mac system monitor, you can optimize your computer’s performance by stopping hovering processes or closing heavy apps. And here are the buttons you will need:

Force a process to quit – close the heavy app easily with a Close button. Select the process and click the “X” icon.

How to see CPU usage graph

Besides the main window, the Mac CPU monitor can be viewed in separate windows. Go to Menu Bar → Window → and select CPU usage or CPU history.

How to see CPU usage in Dock Panel

In most cases, the user does not need complete and comprehensive information about the Mac system monitor. Therefore, you can change the app’s icon in the Dock to monitor CPU usage. All you need to do is open a context menu and select what would you like to see.

Now you know everything about the Mac resource monitor and can successfully deal with an unresponsive system. If you use Activity Monitor mostly to view the heavy apps and force quit them, we would recommend the great free app Memory Cleaner. It is designed to clear RAM memory but has some additional features which let you force close processes, including those which run in the background.

If you’re finding that your Mac fans are running a lot more than they used to, you might want to check out whether a couple of Spotlight processes are consuming more than their fair share of CPU cycles.

Ever since the latest Mavericks update, I found that my MacBook Pro seemed to be running hot a lot of the time, with fans ramping up to high levels to cool it. Checking Activity Monitor didn’t seem to be shedding much light on things at first glance. The only two processes using an unusual amount of CPU were mds and mds_stores. These are two processes used by Spotlight when indexing, so I didn’t think too much of it – Spotlight has to do its indexing sometime, right?

But several checks later, these two processes seemed to be helping themselves to significant chunks of CPU on a regular basis, at which point I did some Googling.

I started by disabling Spotlight altogether to confirm that it was the culprit. To do this, I went into Terminal and entered:

The fans spooled down and all was back to normal. Spotlight was indeed the culprit.

I briefly considered leaving Spotlight off until the next OS X update, but that proved too much of a pain. I keep my most-used apps in the dock, but everything else I habitually launch from Spotlight. CMD-space plus the first letter or two of the app is just too convenient to give up. So I did some more Googling – after switching Spotlight back on with:

The first tip I found was here, where it suggested deleting the Spotlight database and forcing it to re-index. You can do this in Terminal again:

Top tip: set this going overnight, as the re-indexing takes a while.

This helped quite a bit, but the mds process still seemed a little greedy. More Googling led me to a suggestion to remove from Spotlight’s indexing any directories with frequently-changing content, especially those used for online backup. You can do this by going into System Preferences, clicking the Privacy tab and then drag-and-dropping onto it any directories you don’t want it to index.

I added my CrashPlan, MobileSync and Dropbox folders – three specific suggestions I’d found – and then for good measure added some others with frequently-changing content.

This did the trick: my fans stayed on low, and Activity Monitor showed the mds processes consuming only tiny amounts of CPU.

I’m not sure how general an issue this – hence making this an aside – but if you’re finding your Mac running hot, it may be worth checking out.

How to find which program is using CPU on Mac – Guide

It is the part of your computer that informs all other parts how to work, which programs to start, which images to display, and much more. Your CPU utilization – in the simplest terms, how much power the CPU is using – is measured as a percentage. When the computer is idle, CPU usage should be in the single digits or low. When running videos, games or other intensive applications, the CPU usage should increase, but never stay at 100% for a long time. If you’ve noticed performance issues such as slow startup times or lagging applications, check your computer’s current CPU usage. This way, you can ensure that the CPU usage percentage stays in a healthy range when your computer is idle and running at high speed.

Your Mac comes with a built-in utility designed to display CPU and GPU usage, as well as lots of other useful performance information. This activity monitor can be accessed through Spotlight or found in the Utilities folder. You can also configure it to display real-time CPU usage information directly in your Mac’s Dock. Mac OS X comes with a utility that lets you monitor which applications and processes are making the most use of your MacBook Pro’s CPU. Launch Activity Monitor to view your computer’s disk activity and usage, examine network traffic, examine system memory, and view real-time CPU usage statistics.

When buying a new Mac, Apple gives you just enough information about the system’s hardware to make a good comparative choice between the different models, but the company keeps the exact hardware details hidden.

For example, when shopping for a new MacBook Air, Apple tells you in the specs that the base CPU is a 1.6GHz dual-core Intel Core i5, Turbo Boost up to 3.6GHz, with 4MB L3 cache, but doesn’t reveal the specific model.

Indeed, even after you’ve purchased a Mac, the information about the exact CPU model is hidden from the “About this Mac” system report. This is fine for most users, but power users or those looking to compare there Mac’s performance to an equivalent PC may want to know exactly which CPU is powering their computer.

How to Find Your CPU Model Using the Terminal

Every Mac has a Terminal in which you can type various commands to receive an output. Even if you’re looking at a Mac in the store, you can use this command to find the exact CPU model. To do that, follow these steps:

1. Use Finder to tap on Applications and then Utilities
   
2. Click on Terminal at the bottom
   
3. Type the CPU command: sysctl -a | grep brand and hit Enter

The information displayed will be the exact CPU model of your Mac. It should look something like this:

How to Find the CPU Model – External

Thankfully, third-party resources, such as the excellent EveryMac.com, have stepped in to provide a wealth of details about every Mac ever released. But to use that information, you’ll first need to know your specific Mac model and then take the time to browse the EveryMac website.

What if you just quickly want to verify your Mac’s CPU model? Or what if you’re working to repair or troubleshoot someone else’s Mac and don’t have all the info about the system immediately available? Well, you’re probably not surprised to learn that there’s a Terminal command that can show your Mac’s CPU model. Here’s how to use it.

First, launch Terminal, which you can find going to the Applications folder then the Utilities folder (or by searching for Terminal with Spotlight).

Open Terminal then enter the following command at the command prompt:

$ sysctl -n machdep.cpu.brand_string

You’ll immediately see a new line of text with the exact make and model of your Mac’s CPU. On my MacBook, this command returned the following line:

Intel(R) Core(TM) i5-8210Y CPU @ 1.60GHz

EveryMac.com provides a summary of the MacBook Pro using this processor, including details about the processor and all of the rest of the hardware that came with this model.

A Google search for i5-8120Y CPU reveals its complete details listed at Intel’s website, including important information such as TDP and recommended price.

Intel has kept the same Core-series naming scheme for several years, meaning that lots of CPUs share similar frequency characteristics even though they offer far different performance levels.

By identifying your Mac’s specific CPU, you’ll be able to more accurately compare your Mac to other Macs and PCs, helping you either make an initial purchase or decide if it’s worth it to upgrade.

Your full breakdown on Mac’s Task Manager and how to use it.

When changing from Windows operating system (OS) to Apple’s Mac OS X, you may feel strange with the new platform and features. Changing settings will often feel completely foreign on this new operating system.

One of the biggest learning curves in switching from Windows to a new Mac computer is learning how to end a task with the help of the Mac equivalent of Windows Task Manager. In Windows OS, it’s very easy to stop a running process by opening Task Manager and select “ End Process ”.

Mac also has a Task Manager application but with a different name: Activity Monitor.

Features of Activity Monitor application are very similar to the Task Manager in Windows. On top of ending any active processes, you can also:

• Monitor CPU usage to see the percentage of CPU capacity that each application takes up
• View the energy impact of each application
• See the total disk activity used by each active process on your computer
• View network usage for each application
• View the memory usage for each running application
• See an overview of all cached content that has been uploaded, downloaded, or dropped on your computer

You can easy to view, manage and close any active processes that are running in Mac OS X. Within Task Manager, you can also view CPU

How To Open Task Manager Mac

Running Task Manager in Windows is easy. Simply use the keyboard shortcut Ctrl + Alt + Del, Ctrl + Shift + Escape, or right-click on the menu bar and select “ Start Task Manager .”

Running Activity Monitor in Mac OS X works a little differently. You can open Activity Monitor by opening up Finder , going to Applications > Utilities and then select “ Activity Monitor ” application.

Simplest Way To Open The Mac Task Manager

There is another way that could help you to open “Activity Monitor” program easier and quicker.

Simply press Command + Space key to launch Spotlight search field.

Type “Activity Monitor” in the search field and press “Enter” or “Return.”

Use Spotlight to open Activity Monitor: a Mac Task Manager

The Activity Monitor is a powerful Task Manager application as it’s not only displaying running applications under user-level but also shows running applications under system-level or kernel level and a few other processes.

If a program is running in your Mac computer, you can find it with Activity Monitor (Mac Task Manager or Task Manager Mac), never miss any tasks.

It allows you to sort processes by ID, name and memory usage. Also, you can search for a specific process that matches characters or names.

The Activity Monitor application can also use to force quit Mac apps when they are unresponsive. To doing so, select the application you want to force-to-close from the list in Activity Monitor and then click the ( X ) icon at the top-left corner and choose “ Force Quit .” The selected application will be terminated immediately.

You can also use Force Quit Application to close any unresponsive apps by pressing the key combination: Command + Option + Esc to bring up Force Quit Application. Next, choose the application you want to close and click on “ Force Quit .”

Have any questions about Activity Monitor application?

Sometimes your Mac may not run as smoothly or as quickly as you expect. And the culprit may be a single application. A lone app can bump into performance issues, slowing down not just itself but your entire computer. An app may even freeze or become unresponsive to the point that you can’t close it the usual way. Whatever the problem, one tool that can help is Activity Monitor.

Built into macOS, Activity Monitor shows you a list of all running apps and processes and reveals the biggest hogs based on CPU, memory, energy use, disk use, and network bandwidth. And if a specific app is unresponsive and can’t be shut down the traditional way, you can force it to close. Here’s how it works.

To open this tool from Finder, click the Go menu, browse to Utilities, and then launch Activity Monitor in the window that appears. The utility starts by showing every running app and process based on CPU resources. Each column for CPU shows a useful result, but the stats for CPU percentage are the most helpful for app troubleshooting.

You can sort the list of apps based on the highest or lowest numbers by clicking on the heading of each column. A graph at the bottom displays the total numbers for CPU percentage and other factors.

Activity Monitor can provide insight as to what apps are using the most resources on your Mac.

Monitored activities

You can switch views by clicking the tab in the upper right of the Activity Monitor. CPU is the first tab, and the default view the app opens.

On Macs with a discrete graphics processor, the GPU section appears after CPU. This shows which apps are the most demanding on your graphics processor.

The Memory screen shows the amount of memory used by each running app so you can find any chewing up more than its fair share. The bottom of the screen reveals the total and used amount of memory on your Mac. The stat for Swap Used can tell you if your Mac is copying too much data between physical memory and your hard drive’s swap file, a sign that you might need more RAM.

The Energy screen is of value on a laptop as it reveals which apps are consuming the most juice from your battery. The bottom of the screen displays the overall energy impact and the battery charge.

The screen for Disk tells you how much disk activity an app is generating in terms of data written to and read from the disk.

The screen for Network reveals how much network bandwidth an app is using.

Troubleshooting performance

For troubleshooting slow or unstable apps, the screens for CPU and Memory are generally the most helpful. If an app is using so many resources that it’s slowing down your computer, try closing it to see if your Mac bounces back.

If the app refuses to shut down the normal way within the app, select it in Activity Monitor and click the Stop button (the octagon with an X) at the top. Then in the pop-up that appears, click Quit to see if the app shuts down without any fuss. If not, click the Force Quick button to force the app to close.

You can stop apps from running from within Activity Monitor.

This really depends on the settings and the use. If you are using it for widgets or somewhat infrequent updates, CPU usage is below 10% for most cases and 2-3% when idle. During active use, use the setting descriptions below to choose the best option for you. On Mac these settings are found in the Duet Mac app in your menu bar when you hover over your connected device. On Windows these settings are shown in the Duet PC app in your system tray.

Regular vs. Retina vs. High Resolution

Regular resolution uses the lowest CPU. It is perfect for most use cases and puts almost no stress on your computer (between 15-25% for active use).

If you either want more space or very sharp retina resolution, you should use retina or high resolution. However, the display has four times the pixels and therefore increases the load on your GPU and CPU by 2-3x.

60 FPS vs. 30 FPS

If you want the maximum quality experience go with 60 FPS. This will require more CPU power but provide an incredibly smooth display. However, if you’re on the go and don’t mind running at the same frame rate as a television, choose 30 FPS. It uses about half the resources and will help your battery last longer. In cases where you are having trouble running the max quality 60 fps smoothly, 30 fps will give you more responsive performance by lightening the load on your CPU.

Energy Efficient vs. High Power

The last option will affect image quality. If you are using it on the go and not plugged into an outlet, Energy Efficient will suit you best. If you’re plugged in and have a modern Mac, you should go High Power! The image is clearer and you’ll get a great experience. High Power mode uses about 10-15% more resources than Energy Efficient mode.

If your Mac has been slowing down over the years, it’s probably time to give it some maintenance and care. You don’t need to break the bank to have better speed performance when it comes to your iMac or MacBook. Instead, we’ve made a list of things you can try to increase the speed of your Mac without the need for a replacement.

Close power-hungry programs

One of the simplest things you can do to increase the performance of your iMac or MacBook is to close any and all apps or programs that you’re not using. Your Mac might be dedicating memory and CPU power to programs that you’re not actively using. This should free up space and workload from unwanted programs that are stealing performance.

There’s also something called Activity Monitor which shows all the processes going on with your Mac. You can open Activity Monitor in System Preferences > Utilities or search and open by pressing Command + spacebar. Some apps and programs use up more power and resources than others. Activity Monitor breaks down the consumption levels of each program you have currently opened by CPU, Memory, Energy, Disk and Network.

Select the CPU tab and you’ll be able to see how much CPU power each app or program is using. Close the ones you’re not using especially if they’re using a high amount of CPU power. Activity Monitor is a helpful tool to check the consumption levels of your apps and programs.

Clean up your start-up

Those pesky apps and programs that launch every time you start up your system might be the culprits behind your slow speeds. Open up System Preferences and click on ‘Users & Groups’. From there, select the ‘Login Items’ tab to view which apps and programs are set to launch when powering on your iMac or MacBook. Select the program you don’t want to launch during start-up and click on the minus sign at the bottom of the list to delete.

iCloud syncing

Syncing your files and photos with iCloud across multiple desktops and devices can slow down your Mac too. When using iCloud, try to avoid storing large files and documents onto your desktop for storage. Only storing the documents and files that are necessary will help speed things up and will have you spending less time waiting for all your files to sync.

This includes syncing your photos on iCloud. If your Mac is too busy syncing all your photos to all your devices and vice versa, you can always turn off iCloud Photos on your device to save your Mac from working too hard and slowing down its performance.

Free up storage space

It’s no surprise that your Mac is so slow when you’re running short on storage space if your storage capacity is almost full. Photos, videos and music are the biggest files that take up a lot of storage space.

A lot of people think that purchasing iCloud will be the solution to low storage space but that’s not the case. If you delete your files off your Mac after backing them onto iCloud, you’ll delete them from all your devices. If you already have iCloud and it’s synced across all your devices, a lot of files and documents are probably sitting on your Mac eating up storage space. For example, pictures you’ve taken from your iPhone synced to iCloud will sit on your Mac using up storage.

It might be better to turn off iCloud photo sync on your Mac. There are other services you can use to back-up all your files and documents on the cloud so that it’s possible to delete them off your computer. Services like DropBox and Google Drive have the same ability to back-up your files such as photos onto the cloud without having to store them on your Mac for them to be accessible.

Your music downloads can also take up a lot of storage capacity on your Mac. You can save storage by offloading your music to an external hard drive to free up space on your computer. You can also pay for streaming services like Apple Music which has a feature that lets you move all your music onto the cloud so that you can delete it from your Mac and access it on any of your devices. You also get the benefits of streaming Apple Music to listen to any song or artist without having to download any of the songs onto your Mac if you have access to data or Wi-Fi.

Delete old and unused files, empty the Bin

A quick and simple way to free up some storage space to help increase the speed of your Mac is by deleting old and unused files and emptying your Bin. It’s a good idea to audit your Mac every now and then for old and unused files and documents. Keeping them stored locally when they’re not being used just takes up storage space and slows down the performance of your Mac.

Don’t forget to delete items from your Downloads folder. Open ‘Finder’ and access your Downloads folder to delete items to your Bin. The Downloads folder is often overlooked and holds a lot of documents and files you might have forgotten about.

Back up your old files and documents to an external hard drive and remove them from your Mac. If you no longer need them, you can always delete them from your computer. Remember to empty your Bin after deleting them. Your deleted files and documents will still take up storage space in your Bin if you don’t empty the Bin.

You can set your system preferences to regularly empty your Bin, which will save you the trouble of manually doing it yourself. Click on the Apple logo in the Menu bar, choose ‘About This Mac’, click on ‘Storage’ then click on ‘Manage’. From there, you’ll be able to set your Bin to delete automatically, which will occur every 30 days.

Reduce or turn off graphics

Apple computers can normally run MacOS without any issues, but sometimes they can be working too hard to maintain performance. Reducing or turning off graphics can help speed your Mac up.

Some people prefer to turn off their Dock to prevent slow down. To do this, click on System Preferences, Dock, and untick the following boxes:

• Magnification
• Animate opening application
• Automatically hide and show the dock

You can also click on ‘Minimise windows using’ and change the Genie Effect to Scale Effect.

The final straw

If all else fails, the last thing you can try is to reset your entire Mac and do a clean reinstallation of the OS. This should be considered a last measure as you’ll need to completely delete your entire boot drive. It will clear all the files in your System and User Libraries that were built up throughout the years.

We suggest backing up all your essential files, documents, pictures, music and anything else you might need once you’ve installed your OS. In the end, if worse comes to worst and your Mac doesn’t have any improvements, it might be time to find a replacement.

What your Apple Mac’s running very slow? it takes much time to open up the app after clicking on the App icon? don’t worry about it.

Activity Monitor can be used for more than just managing tasks and killing processes, it can also turn the Mac OS X Dock into a live system monitor where you can keep an eye on processor usage, CPU history, network activity, disk activity, or RAM use.

This is really handy if you like to keep an eye on a system resource, as many Mac users do, and since Activity Monitor is bundled with the Mac there are no third party apps to rely on, it’s all built into MacOS X.

How to Monitor System Activity from the Dock in Mac OS X

Transforming the Activity Monitor Dock icon into a live system resource monitor is simple, and makes for an extraordinarily useful tool to keep an eye on various aspects of system behavior:

1. Launch Activity Monitor, found in /Applications/Utilities/
2. Right-click on the Dock icon and scroll up to the “Dock Icon” submenu and select one of five available options:
   • Show CPU Usage – this is a live gauge of processor activity on the Mac, each CPU core is shown as a separate bar, this is probably the most useful of the five choices (shown up top)
   • Show CPU History – this shows processor load and use graphed over time, each CPU core is shown separately
   • Show Network Usage – displays a graph of incoming (green) and outgoing (red) network traffic, this can be helpful if you’re on a sketchy internet connection or are carefully conserving bandwidth
   • Show Disk Activity – shows a live graph of disk reads (green) and writes (red) in the same format as Network Usage
   • Show Memory Usage – displays a pie chart of current RAM usage and allocation on the Mac, green is free memory, red is wired, yellow is active, and blue is inactive memory

You can close out of the primary Activity Monitor window but keep the Dock icon active, to do that just click the Red close button, which will ditch the window but leave the app itself running, thus maintaining the live activity icon in the Dock. You can also choose to minimize the primary window to get the same effect, though the minimized window will maintain itself in the Dock as well.

If you find yourself using this often, you may want to pin Activity Monitor to the Dock by right-clicking and choosing “Keep in Dock” from the Options submenu. I keep this active in my Dock at all times, but I’m a bit of a geek and a bit obsessive about monitoring CPU activity and performance, making sure things are running at optimal conditions at all times.

Here is what the CPU usage looks like on a Mac with quad core CPU (the number of bars represents the number of cores or processors):

Here is what the memory usage pie chart looks like:

And here is what Disk Activity and Network Activity look like:

If the Dock isn’t your thing, the iStat Menu bar item offers similar features in the menu bar.

Personally, I rely on the Activity Monitor Dock icon all the time for CPU monitoring, it helps to identify when a process has gone errant or haywire, but everyone has different requirements and needs. Try it out and see if it works for you.

The Ultimate Guide for macOS

Discover which apps are draining your MacBook battery with these helpful tips.

If you’re worried that your MacBook battery is draining quicker than usual, then chances are a particular app is using all its resources in the background. To quickly check, just click on the battery icon in the top-right corner of the Finder menu. The drop-down menu will show you which apps are using the most energy. The app at the top of the list is the worst culprit, like this:

See detailed battery statistics

If you want to find out more about the energy use on your Mac, then the Activity Monitor app can help. You can find it by opening LaunchPad, or by clicking on Go in the Finder menu, then Applications. Next, click on Utilities and double-click on the Activity Monitor app.

Along the top of the Activity Monitor window, you’ll five tabs. These let you see which apps are using the most processing power, memory, energy, hard drive data and network bandwidth. If you’re worried that a particular app is using all your Mac’s CPU power, click on the % CPU column to sort results. The application using the most CPU power will now appear at the top.

Feel free to click on the other tabs to explore how the apps and services running on your Mac are affecting it’s total power and energy use.

If you’re the sort who likes to keep on top of the apps running on your system, then you’ve probably already encountered those stubborn processes that, despite quitting the application, keep behind-the-scenes core or periphery application processes running in the background, consuming processing power and draining your battery. Or, out of the blue, the Mac slows down because one of these processes start to run, suddenly eating up 100% of the CPU. Ending this process will improve the overall performance of the computer, especially in systems with less RAM.

Then there are things like removable media and mounted disk images, where processes hidden from plain view could well prevent the media from safely ejecting. This is a situation that no doubt everyone has encountered at least a few times…

How to View Processes

There are various ways to view running apps and processes in macOS: looking at the Dock, opening the Force Quit Applications window, using the Terminal, and finally by checking Activity Monitor. Also, certain third party Mac monitoring apps, such as iStat Menus, can allow you to view the processes by clicking on the CPU icon in the menu bar.

Activity Monitor, the built-in system monitoring utility, is the best way to view all processes currently running on the Mac, and from here manage them based on how they affect the computer’s performance. Using the ‘view’ menu allows users to choose which processes are shown in each of the five categories, be that all processes hierarchically, user processes, system processes, active processes, and more.

The Most Common Processes Mac Users Complain About

Spotlight

At the core of every search performed on a Mac is Spotlight. Whenever you search for a file, it is Spotlight that will locate it for you, because it indexes the contents of the computer. Think of situations such as migrating to a new Mac, after a complete system erase and new install, a major macOS upgrade, and the like. In these cases Spotlight will consume a lot of your computer’s computing power. There are situations where it’s not important to have a fully indexed Mac, and at these times it makes sense to disable Spotlight to save resources.

Faces, Memories, Photos

Indexing faces and objects was promoted by Apple as one of the key features of the Photos app and macOS Sierra. While in theory it is a nice feature, in actual fact it became a source of frustration because users couldn’t understand why it took so long to index the photo library. Some users had huge photo libraries, others smaller, but the result was the same slow indexing process. According to Apple support, the ‘feature’ has a daily limit on the number of photos it is able to process.

That’s the photoanalysisd process, which sometimes launches and demands CPU resources. As a result, what you’ll notice is a slow Mac that can become hot if the process takes too long to run.

What Processes to Kill With Activity Monitor

When you open Activity Monitor, a long list of items appears. When looking at the process names, the vast majority of them may sound like gibberish to you, and you’ll be tempted to kill all of them. That won’t always be such a good idea, though, so it is important to ask yourself: ‘Which processes do I need to kill?’

1. Look for processes with names similar to those of closed apps. It’s safe to quit processes that resemble app names you have already quit.
2. Close Rosetta applications. These are PowerPC processes running on an Intel-based Mac, so it doesn’t make too much sense to allow them to eat into the physical resources of your Mac.
3. Quit disk image processes. Sometimes the only way to unmount a stubborn disk image is by killing the associated disk image process.
4. Quit processes using high amounts of CPU. In the CPU tab click on the arrow until it is facing downwards. This will help you identify the processes that are demanding high CPU resources.
5. Kill all duplicate processes by clicking on the Process Name tab to view the processes in alphabetical order, and quit any secondary items with the exact same name.

Please note that there are some processes that shouldn’t be messed with, especially those run by the root user. If you are not certain what a process means, it is better to ask for help from someone who does or contact Apple support.
