Here are my go-to methods to free up memory on Mac. Get CleanMyMac X here: Follow these steps as you watch this video:- Check your mem.
1. Remove App Junk
App junk are those programs that tend to remain hidden on your macOS even after dropping them on Trash. However, it is worth understanding that deleting unwanted app manually increases your chances of completely removing some critical programs. Therefore, carefully check the filename before deleting it to ensure that it’s for the intended app.
If you want to ensure that you delete all the program junk from your macOS Big Sur, follow the following steps:
Step 1. Take note of the apps you’ve sent to Trash and jot them down. Afterward, find the app junk and the files they are related to.
Step 2. Visit the app location to find the associated programs. Open Finder, Select “Go” and choose “Go to Folder”.
Type “/Library/Application Support” and click “Go”.Go to the folder in macOS Big Sur
If you want to locate a particular program for a specific app, follow the following commands:

- Library apps – /Library/Application Support/
- File Support Cache – /Library/Caches/
- Launch Agents – /Library/Launch Agents/
- Preference Files – /Library/Preferences/
- Application Support Files – /Library/ Application/
- Binary and Dock Items – /Application/
- Start-Up Items – /Library/Startup Items/
- Saved App States – ~/Library/Saved Application State/
2. Clean Your Download Folder
Are you still puzzled on how to get rid of all those PDF files you obtained from the internet or the images you opened after reception from friends or relative? All these files end up in the Downloads folder on your macOS. Without wiping them off, they end up taking up a considerable chunk of your hard drive space. To get rid of file junk from your downloads,
follow the following steps: Clean Download Folder
- Visit the Downloads folder near the Trash Can icon to reveal downloaded items.
- Click the “Open In Finder” button to find the “Downloads” folder, which contains all your downloads.
- Once here, you can either press Command + A to select all files or choose each file one at a time.
- Once you’re done highlighting the intended files for deletion, drag and drop them in the Trash Can.
3. Use Storage Optimization Tool on macOS Big Sur
The new macOS Big Sur has a new storage optimization tool that ensures the device has an optimized storage usage at all times by avoiding space wastage. Also referred to as the “Storage Tool”, this feature offers additional space in your hard drive for you to store other programs and files.
To activate the storage optimization tool in your macOS Big Sur, follow the following procedure: Visit the “Apple Menu” located on the top-left of your screen.
Click on About This Mac > Storage > ManageUse New Storage Optimization Tool on macOS Big Sur
You’ll see a pop-up message with several options. Click on the “Optimize Storage” button. Once activated, the optimizer will automatically arrange your files, removing any program junk to free up space. The reason why the storage optimization feature excels in the macOS Big Sur is that the device has an enhanced space for additional storage.
4. Clean Cache on your Mac
In simple terms, a cache is a type of temporary files that enable the macOS Big Sur to operate efficiently. There are various types of cache files. They include Browser cache, System cache; and User cache. Although these caches are helpful, they are temporary and can usurp a large space on your macOS disk.
Clearing Browser Cache on Your macOS
If you are a heavy internet user, you may end up clearing megabytes of cache files on your macOS Big Sur. The official MacBook browser is Safari, and you can remove the cache by following the following steps:Show Develop Menu in Safari
- Click the Safari icon to open the browser.
- Go to the menu and click on “Preferences”.
- Go to the “Advanced” feature and tick the “Show Develop” in the menu bar.
- Click the “Develop” button in the menu bar and choose the “Empty Caches.”
- Close the Safari browser for cache clearance to be complete.
Clear System Cache and User Cache
The system and user caches are the temporary files that let you use your macOS on daily operations. For example, when you listen to music or view a video on your MacBook, the information is stored in the system cache file. The device can, therefore, locate the file quicker and easier on a subsequent command. With time, these caches can occupy a large space on your macOS Big Sur. If you’d like to clear all cache from your macOS or delete a cache belonging to a particular application, here’s the procedure
Terminate the operations of all applications.Launch “Finder”.
Select “Go” on the Finder menu and choose “Go to Folder”.
Type ~/Library/Caches/ and click “Go”.
Find the cache file related to a specific app and choose the items you need deleted and drag them to the Trash Can.
5. Use Cloud Drives
Is your MacBook filled up because of storing a lot of programs and apps? Additionally, you may lose your personal data by frequent misplacement of your USB flash drive. That’s why software developers have created cloud-based storage apps to help you to free up space on your macOS. There are several cloud drives you may consider, but each operates differently with different operating systems. Below are some of the best cloud drives for you macOS Big Sur.
Google Drive. Albeit Google Drive was initially intended for storage purposes, it expanded its featured tools by incorporating an office suite that comprises Google Docs too. Fr merely having a Google Drive, users get 15GB free storage space. However, for additional space, you’ll have to incur monthly subscription fees.
iCloud Drive. This Apple cloud-based storage software works best with Apple’s latest gear on the macOS Big Sur. When you use it on any macOS device or an iDevice, you get an extra 5GB of free space. It comes with an integrated office suite, although it only contains basic features like Pages, Keynote, and Numbers. iCloud supports Windows but is still not supportive of Android.
Dropbox. Dropbox free storage is 2GB. The advantage of this cloud storage app is that it’s compatible with different platforms, including Windows, Mac, Linux, iOS, Kindle, Android, and Fire mobile application programs. Dropbox also provides different promotional offerings such as an extra 250MB for just getting started with the tutorial or 3GB extra space for uploading images through the mobile app.

6. Find and Remove Duplicate Files
The daily utility of your macOS may mean having duplicate files. The most common reason why you may have duplicate files is because of program installations. When an essential program feels under threat from other applications, it may duplicate itself to minimize the risk of malfunctioning.Find and Remove Duplicate Files
But if you find an unimportant program with it duplicate, you can install the Gemini 2 App for macOS. Gemini helps you identify, locate, and get rid of duplicate content in whichever corner they lay concealed. Regardless of the capacity of your hard Drive, Gemini can scan it at a lightning-fast speed. Furthermore, the software also locates and removes similar files to ensure you have free space on your MacBook.
7. Use Third-Party Apps
Instead of using the manual method of clearing space, you can use automated software that performs all that work in a fraction of the time. The Clean My Mac app automatically rids your macOS system of junk file and other remnant programs that eat up space in the device. By using the Clean My Mac software, you can clear up space to revamp the speed and operations of your MacBook.
System cleanup in one click
Few things are as frustrating as your Mac telling you it has run out of memory when you’re trying to be productive. But it’s even frustrating when you’ve ignored the problem for quite some time and your Mac’s limitations simply won’t let you put a solution on hold any longer.

Usually, a popup warning isn’t the first sign that something is amiss. You may have noticed that your Mac isn’t running as fast as it used to, with the fan louder than normal as if it’s struggling to carry a heavy load up a hill.
Although Macs are wonderful computers, like any other, they have limitations. Thankfully, there is plenty you can do to resolve this problem and get your Mac operating smoothly again.

How to Fix Your System Application Memory

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. Let’s discuss all these possibilities step by step.
How to 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. You can do this in Mac’s control center, via the Finder in your Dock, or by pressing ⌘ + Space and typing Activity Monitor in the Spotlight.
- 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 to inspect.
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.
But what creates CPU-hogging problems overall and how do they lead to slow Mac performance?
Every Mac has a processor which handles the computing of any task, from opening an app to editing photos. Processors differ in power (expressed in GHz) and efficiency (generally, newer processors are more efficient).
For example, a 9th Generation 2.2 GHz Dual-Core Intel Core i7 processor means that it has two i7 chips, each of which is able to process data at up to 2.2 GHz, and its the 9th iteration of that processor overall.
However, regardless of the power of your processor, if you throw too many tasks at it, it will start to slow because it’s trying to process too much information at once (try opening 100 Google Chrome tabs), creating a bottleneck. That’s why you can have applications not responding. So you need to do something about it.
App Tamer is perhaps the most powerful smart CPU manager out there. Not only does it show the exact CPU percentage and battery impact each process is taking from your Mac, it lets you create simple rules to prevent certain processes from hogging too much CPU.
To tame any app, just click on it in App Tamer (located in the menu bar), select “Slow down this app if it uses more than” and specify the exact CPU percentage.
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 stop icon in the top bar
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.
Below we list 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.
That's because 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 resource 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 to make it better:
- 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 other 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:
- 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.
Go to Mission Control ➙ switch off the Dashboard
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.
Mac Disk Cleaner
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.
