The obvious and most reasonable explanation is that one or several processes currently running on your Mac are causing your central processing unit to allocate a lot of resources to maintain their operation. In other words, if you encounter high CPU usage on your Mac, the first thing on your to-do list is to look for the “culprit” app or apps.

- Remove Login Items to lower Mac memory usage. Login items are programs that load automatically.
- Review the Memory Report. While your app is running in Xcode, the memory report available from Xcode’s Debug navigator shows the app’s current memory use, along with the highest value seen. The yellow region of the memory gauge indicates memory use high enough to trigger a warning. The app risks termination by iOS if its memory use enters.
- And running CleanMyMac's maintenance scripts regularly prevents problems occurring in the first place. Best of all, all these apps are available to try for free on Setapp, along with over 200 high-quality macOS apps. So check your Mac for problematic processes now and see what you find.
- Mac OS X is a slick, powerful operating system, but there's a cost to all that gloss. Most users don't ever bother to check, but many of the apps they use every day are notorious RAM-gobblers.

Your system has run out of application memory - Fix it
Mac memory usage is often occupied by apps, even browsers like Safari or Google Chrome. In the most dire circumstances, your Mac will toss a warning at you: 'your system has run out of application memory.'
Don't despair – it's solvable. The first thing to note is this is a natural issue; your Mac has a limited amount of RAM. Though more expensive Macs have more RAM, even they can butt against limitations when too many applications are running.
It may also be an app that is hogging all of your resources. This is especially true of older applications which haven't been optimized for modern computer architecture. Websites may also be a culprit.
Check RAM usage on Mac
To check your RAM use on any Mac, take the following steps:
- Open Activity Monitor from your list of applications
Note: You can do this is the Mac's control center, via the Finder in your Mac's dock, or by pressing command-space and typing 'Activity Monitor' in the Spotlight search field. - Toggle to the 'Memory' pane in the Activity Monitor window
As you see in the above screenshot, Activity Monitor shows you all of your processes, sub-processes, and how much memory each is taking up. The most pertinent portion of the window is the bottom, where it shows you the total memory usage, and how it's affecting your Mac.
A better way to monitor your Mac's memory use is with iStat Menus. After installing the app, it makes a home in your Mac's menu bar, and monitors just about everything, including memory, CPU, GPU, disks, and network usage.
You can choose which systems you'd like to monitor in the app itself. Only the items you're monitoring will have an icon in your menu bar. A simple click on the menu bar icon surfaces a drop-down menu of how your Mac is performing at the time, and hovering over each graphic brings up a larger menu, as you can see below.
How to check CPU usage on Mac
Checking CPU use on your Mac is similar to the steps above for checking memory use. For Activity Monitor, you'd make sure to highlight the 'CPU' section of the window. This will show you all the processes using your Mac's CPU at the time.
Similarly, iStat Menus has a 'CPU & GPU' toggle just above the memory section. Activating that will add a CPU and GPU monitor to your Mac menu bar, which has the same interactivity as the memory icon and menu shown above.
How to free up memory on Mac
Knowing how to clear memory on Mac is important, especially if you have a Mac with limited resources. One option is using Activity Monitor:
- Open Activity Monitor on your Mac
- Select an app using a lot of memory
- Click the 'x' icon on the top left of the screen
This is straightforward, but there's a better way. CleanMyMac X has an automated CPU and memory monitors built-in, which can give you a real-time view of memory usage in your Mac's menu bar. It also has a really quick and easy way to free up memory without digging through Activity Monitor and manually shutting down apps.
All you have to do is click the CleanMyMac X icon, select 'Free Up' in the memory pane, and the app takes care of the rest! Oftentimes, it doesn't even shut apps down.
This is a quick fix, but CleanMyMac X takes it a step further in the app itself. Under the app's 'Maintenance' section is an option to 'Free Up RAM,' which helps you clear RAM on Mac. Once you've got this option selected, simply select 'Run' at the bottom of the window, and CleanMyMac X will do a thorough scrubbing of your Mac's RAM, and clear unused files out of the way.
How to get rid of low memory notifications
Most apps are pretty good about how they use your Mac's resources. Having too many open or running in the background can severely limit what your Mac can handle, and is often why a Mac overheats or slows down.
Here are a few tips to reduce high memory usage manually if you're experiencing unique warnings or issues:
Fix 'kernel_task', a high CPU usage bug
You may have noticed through Activity Monitor something called kernel_task absorbing a large amount of processing power. One of the functions of kernel_task is to help manage CPU temperature; you may find that your Mac fan is loud and always on, even if the device isn't hot to the touch.
kernel_task usually performs this way when one or more applications are trying to use too much CPU. Unfortunately, one of the potential downsides is a Mac can overheat to such an extent that internal systems are damaged, sometimes irreparably.
Working through the following steps in this article is one way to avoid similar problems. If none of this work and kernel_task is still absorbing a high percentage of your CPU, then one or more of the following could be the cause:
- Cooling system inefficiency
- A failed or disconnected temperature sensor
- Another hardware issue, including a worn out batter
- Your System Management Controller needs a rest
If you're experiencing severe issues, Apple recommends a system management controller (SMC) reset. It's essentially a hard reset for your Mac, and should help your RAM and other hardware components start from scratch. Keep in mind you won't lose any data in this process.
Reduce memory usage in Finder
One common culprit for RAM issues is Finder, your Mac's file manager. If iStat Menus or Activity Monitor has highlighted Finder as using hundreds of MBs of RAM, there is an easy solution: change the default display for a new Finder window so it doesn't show All My Files.
- Click on the Finder icon in the Dock and click on the Finder menu, then select Preferences
- Click on General. Under 'New Finder windows show', click the dropdown menu and choose any option except All My Files
- Close Preferences, press Alt-Control, and click on the Finder icon in the Dock. Click Relaunch
Finder will now relaunch with new windows opening at the option you selected in step two.
Improve Chrome's Task Manager
Chrome is a popular browser, but it's a resources hog! Chrome uses a GPU Process as standard, which means it speeds up the loading of web pages, which can be great except at times when your computer is struggling with insufficient RAM.
Here's how:
- Open Chrome on your Mac
- On the right side of the Chrome window, select the three-dot menu
- Select 'More tools'
- Select 'Task Manager'
- Select a Chrome process you'd like to kill
- Select 'End Process' at the bottom right of the window
Here's another way to reduce Chrome's use of your Mac's memory:
- Open Chrome on your Mac
- On the right side of the Chrome window, select the three-dot menu
- Select 'settings'
- Scroll to the bottom of the page and select 'advanced'
- Scroll down to 'System,' and toggle 'Use hardware acceleration when available' off
This will affect how Chrome runs on your Mac, and your experience won't be as smooth. You can also remove unused or unwanted Chrome extensions to help it use less resources on your Mac.
Get CMM X to free up space
Install CleanMyMac X and streamline the entire process of memory management on Mac. Clever memory usage control done for you.
Clean up browsers
In every browser you use regularly, there are always going to be extensions and popups that take up space and use RAM. You can manage each one manually, or use a tool such as CleanMyMac X to identify and delete them.
In the CleanMyMac X app is a section titled 'Extensions,' which lists each extension you have for your browser or browsers. All you have to do is view the list of extensions, select the ones you no longer want, and remove them. It's really that simple!
Disable login items
Login items, browser extensions, and preference panes, such as Flash, are another common source of memory usage. Most of us have several installed that we rarely use, but which hog memory and reduce performance.
One way to do this is through System Preferences:
- From your Mac menu bar, select 'System Preferences'
- Select 'Users & Groups'
- Select 'login items'
- Deselect items you no longer want active at login
Another way, one that is even quicker, is to employ CleanMyMac to identify and cleanup login items. Football manager 2017 for mac download.
- Open CleanMyMac X
- Under 'Speed,' select 'Optimization'
- Select 'login items'
You can remove all login items, or select the ones you'd like to remove individually on the right side of the window.
Disable desktop widgets
Older Macs running a version of macOS older than Catalina can disable widgets. Desktop widgets can provide a useful shortcut to apps you need to access fairly often. But they can take up processing memory that is slowing your whole Mac down. One way to close them completely is in System Preferences.

Declutter your desktop
Apple's built in decluttering tool is handy for many. All you have to do on your cluttered desktop is right-click, then select 'Use Stacks.' This places all of your desktop files into folders unique to their filetype, like 'screenshots' and 'images.'
A better way is to use Spotless, an app that gives you far more control over how your Mac is organized. It has several triggers for automated cleanup of files on your desktop, placing them wherever you see fit. It's particularly useful for power users who produce several files daily, but don't want to take the time to place each in a respective folder.
You can also select many files on your Mac desktop, and tell Spotless to tidy them up. You always have full control!
Schedule regular cleanups
Constant use of your Mac, or leaving it on all the time, will slow it down over time. Shutting it down and restarting is a traditional way of 'cleaning up' a computer.
We also like CleanMyMac X's scheduled cleanup feature. Telling the app when you'd like to perform a thorough cleaning up of your Mac's system is a method many prefer to shutting down and restarting often. It has the upshot of removing files and folders you no longer use, and cleaning up tasks that are slowing your Mac down behind the scenes. A simple shutdown may not do this.
Keeping your Mac in tip-top shape is critical. While we'd all like to think computers are brilliant little devices that can handle anything, they need some care, too.
All of the apps mentioned in this article help with taking care of your Mac, and protecting your investment. Best of all they're each free as part of a seven day trial of Setapp. Give it a try today!

At times, Firefox may require significant system resources in order to download, process, and display web content. If you are experiencing periods of sustained high resource usage while using Firefox, this article presents some options for you to review.
- The CPU (Central Processing Unit) is the 'brain' of the computer.
- The RAM (Random Access Memory) or Memory helps your computer perform multiple tasks at the same time.
- When your system resources are being heavily used, the overall performance and stability of the computer can be impacted.
- Depending on your operating system, you can review and monitor resource usage through specific tools. See the Use additional troubleshooting tools section below for more information.
Note: If you send performance data, Mozilla will gather data including memory and CPU usage, which will help make Firefox better for future versions.

The latest Firefox version may include performance improvements. Update Firefox to the latest release.
Firefox may use more system resources if it's left open for long periods of time. A workaround for this is to periodically restart Firefox. You can configure Firefox to save your tabs and windows so that when you start it again, you can start where you left off. See Restore previous session - Configure when Firefox shows your most recent tabs and windows for details.
Extensions and themes can cause Firefox to use more system resources than it normally would.
To determine if an extension or theme is causing Firefox to use too many resources, start Firefox in its Safe Mode and observe its memory and CPU usage. In Safe Mode, extensions and themes are disabled, so if you notice a significant improvement, you can try disabling or uninstalling extensions.
- For more information on starting Firefox in Safe Mode and on how to find which extension or theme is causing your problem, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.
Many web pages have content you don't need, but which still use system resources to display its content. Firefox's built-in content blocking can help save resources by preventing third-party tracking content from loading. See the Content blockingEnhanced Tracking Protection article for details.
Some extensions allow you to block unnecessary content; for example:
- Adblock Plus and uBlock Origin allow you to hide ads on websites.
- NoScript allows you to selectively enable and disable scripts running on websites.
If Adobe's Flash Player plugin is installed, rendering Flash content in full screen can be accelerated by hardware. This can ease resource usage in case of a dedicated graphics card.
- Navigate to a page that shows a Flash video.
- Right-clickHold down the Ctrl key while you click on the video player and click Settings… in the context menu. The Adobe Flash Player Settings screen will open.
- Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel.
- Check Enable hardware acceleration is selected.
- Click to close the Adobe Flash Player Settings Window.
Each tab requires Firefox to store a web page in memory. If you frequently have more than 100 tabs open, consider using a more lightweight mechanism to keep track of pages to read and things to do, such as:

- Bookmarks. Hint: 'Bookmark All Tabs' will bookmark a set of tabs.
- Save web pages for later with Pocket for Firefox.
- To-do list applications.

With Multiprocess Firefox, also called electrolysis or e10s , Firefox runs web content for all tabs separately from the main Firefox process for increased security and performance. Using multiple content processes can further increase performance and minimize the impact of content process crashes. You can modify Firefox's performance settings to change the content process limit.
![Reduce Menmory Used By Apps Running On Mac Reduce Menmory Used By Apps Running On Mac](https://cdn.macpaw.com/uploads/images/Optimization - login items.png)
You can set between one and eight content processes. The default is eight. Having more content processes can improve performance when using multiple tabs but it will also use more memory. You can reduce the number of content processes if your computer is running out of memory.
Having many applications running simultaneously may cause your computer to run slowly and other applications to do so as well. By closing down some of the unnecessary applications, system usage will be reduced.
Firefox stores your data in various files in your profile folder. The file used for saving individual website settings might be corrupt. If you delete (or rename) that file, your zoom level settings will be reset but it could decrease CPU usage.
- Click the menu button , click Help and select Troubleshooting Information.From the Help menu, select Troubleshooting Information. The Troubleshooting Information tab will open.
- Under the Application Basics section next to Profile FolderDirectory, click . A window will open that contains your profile folder.Your profile folder will open.
Note: If you are unable to open or use Firefox, follow the instructions in Finding your profile without opening Firefox.- Click the Firefox menu and select Exit.Click the Firefox menu at the top of the screen and select Quit Firefox.Click the Firefox menu and select Quit.
- In your profile folder, delete the file content-prefs.sqlite. It will be recreated next time you open Firefox.
The Refresh Firefox feature can fix many issues by restoring your Firefox profile to its default state while saving your essential information.See Refresh Firefox - reset add-ons and settings for details.
There are a variety of troubleshooting tools that can be used both in Firefox and on your operating system to troubleshoot elevated system resource usage.
Firefox tools
- The Firefox Task Manager (not to be confused with Windows Task Manager) is a great tool to see what tabs and extensions are using the most system resources.
- The about:memory page allows you to troubleshoot specific issues relating to memory (for instance, caused by a website, an extension, a theme, etc.) and sometimes its button may help you instantly reduce memory usage. For guidance on use of about:memory visit about:memory.
