Apart from that, it uses a hammer test, sequential memory blocking, moving inversions and many more complex methods to put a heavy load on the RAM. Having said that, the best part about MemTest86 is that it supports all kinds of RAM from DDR4 to DDR2. It’s also compatible with both PC and Mac having UEFI or Legacy BIOS.

“No matter what I do, my Mac is still slow”, an average tech-consultant hears this phrase multiple times a day. Give a person even the most powerful computer, and pretty soon it will be cluttered with apps, extensions, and things that are too much for it to handle. To reverse it, one has to go back and сlean up the mess, removing memory agents one by one. Prepare for a fight — every byte of memory is at stake. So let’s put your Mac on a diet and get it more free RAM to breathe freely.
To show you where it is, let’s look at your Library. This is where your macOS keeps application components, widgets, and various cache archives. This part of your Mac is hidden from view for a reason. Messing up a few folders here may break your Mac. But let’s take a look: Click on Finder Go (in the top menu). Now paste in: /Library/Caches. It empties out all the trash files to free up disk space on your Mac machine. It completely removes leftover files of applications that you uninstall. It provides real-time information about CPU and network usage. It helps free up inactive memory for your Mac’s processor. Read Also: How To Clear or Reduce System Storage On Mac? If you have been busy using your computer opening up lots of programs, big files like photographs or videos, or just been using your computer a lot you may w.
First, remove desktop clutter. Get a combination of Setapp apps that clear away unneeded desktop files.

How do you know your Mac is low on memory? Floating “rainbow wheels” aside, you may notice your Mac now takes ages to load. You’ll also see many browser applications crashing. You’ll be also thrown warning messages as “Your system has run out of application memory”. To help it, you should first visit the Activity monitor to see memory usage on Mac.
How to check RAM usage on Mac
Go to Applications and type in Activity Monitor in the search bar. This invokes a good old Activity Monitor that should tell how much free memory you’ve got left.
A shortcut to open Activity Monitor:
Press F4 and start typing Activity Monitor in the search bar.
I’ve attached a screenshot from my Mac and as you can see my memory usage almost reached full capacity. Here’s what it all means:
App memory: taken by apps and processes
Wired memory: reserved by apps, can’t be freed up
Compressed: inactive, can be used by other apps
Swap used: memory used by macOS
Cached files: memory you can really use
Notice the colored graph under Memory Pressure. If your graph is all but red and yellow, your Mac is really gasping for fresh memory. It seems counter-intuitive, but “available memory” your Activity Monitor is not that important after all. In fact, it’s a system intended behavior to use all memory resources when available. On the contrary, the Memory Pressure graph is much more telling, so grow a habit to check this graph in the Activity Monitor every now and then.
How to check CPU usage on Mac
Open the CPU tab in Activity Monitor to keep in check CPU-heavy processes. Normally an app would be using 0-4% of CPU. If it takes abnormally more than that, go inside that particular item in the list and press the Quit button.
How to free up memory on Mac
Tip # 1. Remove Login Items to lower Mac memory usage
Login items are programs that load automatically upon Mac startup. Some of them covertly add themselves to the list and this is no good. If you’re looking to free up RAM, they are the first candidates for deletion. Don’t worry, you’re not deleting the app itself, you just stop it from auto-launching every time.
So, to remove Login Items and at the same time reduce your memory usage of your Mac, you need to:
- Open System Preferences and select Users & Groups.
- Click your nickname on the left.
- Select the Login Items tab.
- Check programs you don’t want to load as your Mac starts.
- Press the “–” sign below.
Now, you won’t see these apps pop up the moment you turn on your Mac. Although this method doesn’t require some superpowers of yours, some special Mac optimization and memory cleaner tools may do the job faster and ensure the smooth performance of your Mac. CleanMyMac X is an excellent example of such software. Here’s how to disable Login Items with CleanMyMac X:
- Download it for free and go to the Optimization tab.
- Check Login Items to see the list of apps that get opened when you start your Mac.
- Click Remove.
As you’ve already come to the Optimization module of CleanMyMac, you can also fix hung apps and heavy memory consumers there. In this way, you’ll free up the solid amount of RAM on Mac — 100% free of charge.
Tip # 2. Free up disk space if Mac is low on memory
The available space on your Mac’s drive translates into virtual memory. This comes to save you when you’ve run out of physical RAM. So now your computer relies on your hard drive space to keep your apps going.
The classic geek rule of thumb holds it that you should keep at least 20% of disk space on your startup drive. Not only this potentially reduces your future spending on iCloud storage but it also keeps your Mac speedier.
What to delete to free up space:
- Large unused files, like movies
- Old downloads
- Rarely used applications
- System junk
But here’s a simpler solution to save your time — clean up your drive with CleanMyMac X— the app I’ve mentioned above. Many users recommend it as an excellent way to free up more space because it searches for large & old files, useless system files, Photo junk, mail attachments and shows everything you can safely delete. Interestingly, it finds about 74 GB of junk on an average computer.
Extra trick: How to free up RAM on Mac with CleanMyMac X
If you have downloaded CleanMyMac, you may also take advantage of its amazing feature — the ability to free up RAM in a few seconds. Try this next time you see “Your system has run out of application memory” message.
- Go to the Maintenance tab on the left.
- Click Free Up RAM.
- Click Run.
As simple as that!
And you can do it even if you download a free version of the app.
Tip # 3. Clean up your Desktop
This tip always comes at the bottom of instructions and unfairly so as it is quite effective. Without even looking at your Desktop I would assume it’s cluttered with mountains of icons. Thing is, your macOS was designed in a way that it treats every Desktop icon as a little active window. The more icons, the heavier memory usage on Mac. So in order to release available memory resources, it’s recommended to keep your Desktop clean.
You don’t have to do it all by yourself. With apps like Declutter and Spotless, every desktop cleaning session will be scheduled in advance and executed automatically. Your only job is to define the rules on how your files should be organized.
Tip #4. Clear cache files
Another way to free up RAM on Mac is to clear it of cache files. Of course, it won’t save you gigabytes of space, but deleting cache regularly, you can help your Mac run faster and avoid system issues.
So, to remove cache files on your Mac, you need to:
- Open Finder.
- From the Go menu, select Go to Folder.
- Type ~/Library/Caches in the field and press Go.
- In the window that appears, you will see all your cache files.
- Press Command+A to select all files or delete files one by one.
- Enter your user name and password to confirm.
If you find some files still in the folder after you emptied it, maybe you have some windows open on your Mac. Just like that, you can save up some space on your Mac. Don’t forget to empty the bin afterward.
Tip # 5. Tune up Chrome’s Task Manager
Although Google Chrome is not the one to blame for massive memory usage, it can indeed affect your Mac's performance. If you use Chrome as your primary browser, you probably have many windows opened there. Chrome runs a lot of processes to ensure a fast browsing experience for you. So, it uses your RAM for storing your tabs, plugins, and extensions. Look at how many entries Google Chrome has in Activity Monitor:
The question then arises, 'Why does Chrome use so much RAM?' The thing is that each process is responsible for a separate plugin or extension of your browser. For example, when a tab unexpectedly falls, you need to refresh it to continue your work there. If one process were responsible for all tabs and extensions, you would need to restart the whole browser instead. Can you imagine how many times would you do that? That’s the proper answer to why Chrome uses so much RAM.
I’ve been using Chrome for some years only to discover (recently) that Chrome had a task manager of its own. You can use it to force quit memory-heavy processes in the browser. It’s a handy tool because it lets you see how a page weighs on CPU usage on a Mac.
- Go to Chrome settings (dotted icon in the top right corner)
- Click More tools -> Task Manager
To free up even more RAM, close the GPU process. The GPU Process, though helpful in theory to accelerate pages, eats up a considerable amount of memory. Click to end it to free up RAM on your Mac.

Tip # 6. Manage RAM usage with CleanMyMac X menu
CleanMyMac X has another useful and convenient feature for managing your Mac’s performance and memory usage. As you install CleanMyMac X and start it for the first time, it’s icon will appear in your menu bar. Click the icon to open the CleanMyMac X menu. Here you can find updates on the current condition of your Mac and perform quick tweaks to increase your Mac's speed. Whenever you feel like your Mac underperforms, open the CleanMyMac X menu to check how much RAM is available and free it up as well.
Tip # 7. Close Finder windows
Okay, suppose you’re still asking yourself, how do I clear RAM on my MacBook Pro/MacBook Air. The next trick is as magical (you’ll see for yourself) as it is time-saving. It’s no secret that each window in the Finder eats up RAM. But how many open windows are there? Some of them are collapsed or stacked in some blind spot on your screen. This Finder command merges all your windows into one. See how to do it:
Click on Finder > Window > Merge All Windows
Now you can manage Finder windows more effectively and free up memory on MacBook.
What else you can do to minimize memory usage on Mac
I’ve saved the easiest tips for the end, as long as these ones are self-explanatory.
- Replace AdBlock (very memory-demanding) with a lighter extension
- Keep fewer opened tabs in the browser
- Restart your Mac more often to free up RAM
- Close all hung-up print queues
That was my take on how to make your Mac a bit speedier to use. If you’re looking for more guidance, check simple ways to speed up your Mac.
Frequently Asked Questions
How to check application memory on Mac?
To check RAM usage on your Mac, go to Activity Monitor (Applications > Utilities). In the Memory tab, you will see all the active processes that are using your Mac’s RAM. At the end of the window, there is a Memory Used graph, which indicates how much application memory is used.
How to find out whether your Mac needs more RAM?
Your Mac may be using almost all its RAM, but you don’t need more if it’s using it efficiently. Open Activity Monitor and go to the Memory tab. The Memory Pressure graph shows the current condition of your RAM: green color means your Mac’s using RAM effectively, while yellow is a sign that some application or process is using too much of application memory. The red memory pressure signals that your Mac needs more RAM.

How To Free Up Ram
You can see the amount of system memory being used on your Mac.
In the Activity Monitor app on your Mac, click Memory (or use the Touch Bar) to see the following in the bottom of the window:
Memory Pressure: Graphically represents how efficiently your memory is serving your processing needs.
Memory pressure is determined by the amount of free memory, swap rate, wired memory, and file cached memory.
Physical Memory: The amount of RAM installed.
Memory Used: The amount of RAM being used. To the right, you can see where the memory is allocated.
App Memory: The amount of memory being used by apps.
Wired Memory: Memory required by the system to operate. This memory can’t be cached and must stay in RAM, so it’s not available to other apps.
Compressed: The amount of memory that has been compressed to make more RAM available.
When your computer approaches its maximum memory capacity, inactive apps in memory are compressed, making more memory available to active apps. Look in the Compressed Mem column for each app to see the amount of memory being compressed for that app.
Cached Files: The size of files cached by the system into unused memory to improve performance.
Until this memory is overwritten, it remains cached, so it can help improve performance when you reopen the app.
Swap Used: The amount of space being used on your startup disk to swap unused files to and from RAM.
To display more columns, choose View > Columns, then choose the columns you want to show.
Ram For Mac
You can use Activity Monitor to determine if your Mac could use more RAM.
macOS is based on Unix, which means that its memory management is pretty robust. However, it’s not perfect, and so you may still see an error message telling you that “Your system has run out of application memory.” What does it mean, and why does it happen? We’ll explain what causes the error and what to do to fix it.
What does “your system has run out of application memory” mean?
macOS stores data used for active processes in RAM. If space in RAM runs low, macOS starts storing data on your main boot drive and swapping it between there and RAM as it needs it. This is known as virtual memory. For this reason, you should always have a decent chunk of free space on your boot drive — 10% is a good rule of thumb. If you don’t have enough space on your boot drive for an application to store temporary files, you will see the error message telling you your system has run out of application memory.
Why does it happen?
There are a number of things that can cause this error message to appear, although, as we said, macOS’ memory management is very good, so if you do see the message, you should take action.
Reasons include:
- Running low on disk space on your boot drive
- Having lots of apps open simultaneously
- Having lots of browser tabs open
- An application “hogging” memory
The best way to avoid seeing the error message is to make sure you keep as much disk space as possible free on your boot drive. The easiest way to do that is to run CleanMyMac X’s System Junk module regularly. This handy tool makes it easy to identify and remove all kinds of junk files. These include temporary files that should have been deleted but weren’t cache files and old logs. You can quickly free up several gigabytes of space with just a few clicks.
How to fix the “Your system has run out of application memory” error
There are other ways you can tackle the problem, too.
1. Restart your Mac
This is the first thing you should try. Restarting your Mac clears the cache and other temporary files and gives back disk space used as virtual memory.

2. Update macOS
Whenever you run into problems on your Mac, it’s a good idea to check if there is an update available, in case the problem is a bug and there is a fix for it in the update.
- Click on the Apple menu and choose About this Mac.
- Choose Software Update.
- If there is an update available, follow the instructions on-screen to install it.
3. Use Apple’s Storage Management
Apple provides some useful tools to help you manage space on your boot drive.
Mac Disk Cleaner
- Click the Apple menu and select About this Mac.
- Choose the Storage tab.
- Press Manage.
- Select Recommendations, and you will see a list of things Apple recommends you do to free up storage space. Decide which recommendations you want to take and follow the instructions.
4. Update apps
As with macOS, it could be that one or more of the applications you’re running has a bug that causes it to hog memory. You should check whether there are updates available for those apps. For apps downloaded from the App Store, you can do that on the Store. For other apps, click the app’s name on the top-left corner of your screen (there should be a “Check for Update” option).
CleanMyMac X has an updater module that can update multiple apps simultaneously and is quicker than updating apps manually. It also has an Uninstaller module for removing apps that you no longer use and getting rid of all the files associated with them.
5. Close apps you’re not using
Keeping apps running in the background when you’re not using them uses up a lot of virtual memory. It’s good practice to quit apps when you stop using them. Press Option-Command-Esc to open the Force Quit menu. If there are programs you’re not currently using, quit them.
6. Close browser tabs
Modern web browsers can have so many tabs open simultaneously that many of us spend all day with dozens of them open. And then we wonder why our Macs are running slowly. Keeping tabs open means they update in the background, taking up memory and other system resources. Bookmark tabs you use regularly and then close them when you’re finished using them.
How to check the memory on your Mac using Activity Monitor
If you’ve completed all the steps above and are still getting the same error message, you’ll need to do some detective work to track down the source of the problem. macOS has a great tool for this work – Activity Monitor. It allows you to see all processes currently running on your Mac and list them according to the system resources they are consuming, including RAM. In this way, you can see which processes are hogging memory and possibly causing the error message, then quit them.
- Go to Applications > Utilities and launch Activity monitor.
- Click the Memory tab to see a list of processes, including applications and browser tabs, that consume memory.
- Select a process or app, and click the “X” sign to close it.
7. Review browser extensions
Obsolete or buggy browser extensions could be another cause of memory problems on your Mac that could lead to the same error message. Take a look at the extensions in each of the web browsers you use and decide whether you use them or whether they can be disabled or removed.
In Safari, you’ll find extensions in Preferences > Extensions. In Chrome, you can access them by typing chrome://extensions in the address bar.

8. Uninstall applications
Some applications take up several gigabytes of space on your Mac, so if you don’t use them, it makes sense to uninstall them. If they were downloaded from the App Store, you could always download them again when you need them. Or, if not, you should be able to re-download them from the developer’s website. Did you know, for example, that Microsoft Word takes up to 2GB of space?

9. Install more RAM
The last resort, and the most expensive option, is to install more RAM in your Mac if you can. Having more physical RAM will mean macOS needs to use your boot drive less often to store swap files. However, not all Macs can have RAM upgraded after purchase, and for those that do, it usually means a trip to an Apple Store or an authorized service center.
How Do I Free Up Application Memory On My Macbook
There are many reasons you might see an error message telling you that your system has run out of application memory. But they all point to the same thing — a shortage of space on your boot drive. So, the simplest solution is to free up more space. However, you should follow the steps above to identify whether there is a problematic app taking up more memory than it should.
