Run MacKeeper to find the most memory consuming apps and processes, then quit them for a faster performance. When apps act up and you see a rainbow pinwheel, it’s a sign you’re maxing out your Mac memory. Clean it in a click with MacKeeper and notice the difference in your Mac speed. MacKeeper shows a quick overview of your Mac RAM. When memory usage reaches a critical threshold, your Mac will become sluggish or even completely unresponsive. When faced with this kind of a nuisance, try a few best-practice methods to reduce RAM consumption and give the system a productivity boost. Restart your Mac. Explore the Memory tab in the Activity Monitor and quit RAM-intensive processes.
Is your Mac slowing down? Do you spend more and more time waiting for applications to do what you want? If so, there is a very good chance that you have high memory usage and need a Mac RAM upgrade.
What is RAM?
Aside from the unnerving “Your computer is low on memory” message, the popup additionally says, “To free up some memory, please close a few applications”. The average Mac user’s natural response to such a dialog is to take a look at the current CPU and memory consumption to see what’s eating up the bulk of it. Subtract Memory Used from Physical Memory to figure out how much free memory is available to you. It’s a good idea not to use all of the free memory; your Mac always needs some free memory to work with. Apps like web browsers can quickly swallow up free memory, not to mention the RAM disk you’re about to create.
RAM stands for Random Access Memory. This memory is temporary and used by the CPU to hold information that processes are actively using on your system. Your Mac slows down when it experiences high memory usage, in other words, when the running applications demand more RAM than your Mac is able to provide. The more RAM available, the better your Mac is able to execute on the tasks that are being thrown at it.
The obvious solution would be to increase Mac RAM, but before we show you how to do that, let’s make sure that your lack of RAM is actually the cause of your Mac slowdown.
Note: Not all devices are able to upgrade RAM, like the MacBook Air and the 2014 edition of the Mac Mini.
How to manually check Mac RAM
Checking your RAM is dependent on the version of macOS that you have installed. You should check your Mac RAM after you have been using your Mac for a bit of time. When you are in the middle of normal daily tasks, follow these steps.
- Open Spotlight Search.
- Type in ”Activity Monitor”.
- Click on the “Memory” tab on the top of the window.
Memory Pressure is the graph you need to study.
If there is mostly green, your system RAM is currently fine. If there is a lot of yellow, the jury is still out. If there is a lot of red, your memory is under strain and your Mac has a high memory usage.
Older OS X versions like Leopard and Lion
For older versions of Mac OS X the steps are the same but the System Memory tab looks a bit different. You’ll want to look for Free and Page Outs.
Free – This is how much free RAM your Mac currently has. If you’ve got a bunch of applications open and there is still a good number of free RAM, then your Mac may have enough memory.
Page Outs – This number tells you how often your Mac has run out of RAM and needed to use the slower hard disk instead. A high number here is very bad and a sure sign that your Mac doesn’t have enough RAM.
Use a Mac memory analysis tool
Another alternative, which will work easily on all versions of Mac OS X, is to use a 3rd party tool to check your RAM usage. I highly recommend CleanMyMac X, which will not only clean and speed up your Mac, it also has a RAM monitoring tool called Menu App.
When you install CleanMyMac X, click on the Maintenance tab in the sidebar.
Here you can free up RAM with just one button. When to use this tool? When your Mac or a particular app hangs up, this feature will temporarily flush memory, helping your Mac to unfreeze.
CleanMyMac X has a free version you can download. So try it out and get to the bottom of your high memory usage problem.
Note: With all above solutions we recommend checking the results on a regular basis until you are certain that your Mac needs a RAM upgrade.
How to upgrade your Mac RAM
If you have reached the conclusion that you need more memory, we are going to show you exactly how to increase your Mac RAM. Don’t worry if you’ve never done it before, as this guide will help you every step of the way.
The first steps are to gain knowledge about your system. This will help ensure that the RAM that you get will be compatible with your system.
Step 1 – What kind of Mac do you have?
Whether you have an iMac, a MacBook Pro, or any other kind of Mac, there is a lot more information to be found out in order to identify your exact system. To get these details, follow these easy steps:
- Click on the Apple icon.
- Select “About this Mac.”
- View your system information.
Step 2 – Do I have space for more RAM in my Mac?
This may not be what you want to hear but it’s possible that you can’t add more RAM to your Mac, even if you wanted to. Let’s look under the hood and see what your RAM situation is like.
- Following on from Step 1, click on “More Info” on the “About this Mac” window.
- The complicated looking System Profiler will launch. Click on “Memory” in the left column.
On the right you will see exact details of your RAM modules or sticks. The “banks” are the slots that the RAM is inserted into. If you have an empty bank or two, you’re in luck, upgrading your Mac RAM just got that much easier.
Step 3 – Check how much RAM your Mac can take
Now let’s really make sure you can upgrade your RAM. Head over to Technical Specifications on Apple Support, find your exact Mac model. Once you find your Mac, click it to reveal a ton of information. What you’re looking for is the information, which will tell you how much RAM your system can work with. Compare it to your Mac’s current RAM (from Step 2) and now you know if you can upgrade your RAM or if you are stuck with what you have.
If you can’t upgrade your Mac RAM, download CleanMyMac X and use all of the cleaning tools to boost your Mac performance. You should also take a look at the performance improving solutions found in How To Fix Mac Running Slow.
Step 4 – Purchasing RAM for your Mac
In Step 3 you navigated to your Mac model and discovered what memory your system could potentially add. Now it's only a matter of choosing your new RAM and we recommend to start with this source. If you're located outside of the US, Google will probably tell you which stores sell RAM nearby.
Step 5 – Installing RAM into your Mac
Adding your new RAM into your Mac is not as hard as it sounds. This is definitely an upgrade that you can perform yourself, as long as you have a screwdriver on hand. The only tricky thing is to know exactly where the RAM is, and that it varies between types of Macs.
Below are handy tutorials to install new memory on your specific type of Mac.

Now you know how to upgrade my Mac memory. Hope this article was helpful.
One of the most common problems that Mac users encounter is low computer memory. Over time, even the most powerful computer will get cluttered with apps, files, extensions , and processes that are too much to handle. To get everything back to normal (because every byte matters), you need to declutter your Mac by cleaning up the mess and removing unnecessary stuff that consumes your computer’s memory.
So when your computer is slowing down, you are likely to notice a “Your system has run out of application memory” message, many of your apps are crashing, or you keep on seeing a lot of spinning rainbow wheels. All these mean your computer is probably low on memory or RAM.
This article will show you how to free up memory on a Mac and other tips to optimize your machine.
What Is RAM?
RAM stands for Random Access Memory and it is one of the most important components of computers and laptops. It is where the computer stores data before being processed. It is a form of volatile memory, where the data is available only when the device is powered on, and everything gets deleted when it is shut down.
Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

Most Macs are equipped with 8GB RAM, but older versions only have 4GB RAM. This is enough if you’re not using RAM-hungry apps, but even then, you’ll still most probably run into memory-related problems in the long run. If you notice that your Mac is taking ages to load or your applications are often crashing, you need to do something to manage your computer’s memory and give it some breathing space.
How To Free Up Ram On Mac Pro
However, upgrading your Mac’s RAM is more complicated than it sounds. Not all Macs have upgradeable RAM , so you need to check first whether your Mac model has a removable RAM or not. In some models, particularly MacBook Air and MacBook Pro, the RAM is soldered to the board and cannot be replaced.
Before you think about installing more RAM, you should first try the tips listed below to free up your Mac memory.
How to Free Up RAM on macOS Mojave
There are several things you can do to manage your Mac memory usage and fix any RAM-related problems you are experiencing.
Reboot Your Mac
The first thing you should do when you free up RAM is to restart your Mac. Refreshing the system solves the problem most of the time, especially if the issue was caused by a minor glitch or an app that crashed. Restarting your Mac will delete the data on your RAM and any disk cache, so things should run smoother and faster after rebooting.
However, if you’re in the middle of something and you’re afraid of losing whatever you’re working on, restarting your computer might not be a good idea. If your macOS has hung because you ran out of memory but you don’t want to lose any unsaved information, you might want to try the other solutions below.
Update Your macOS
It is also possible that your memory problem is being caused by a macOS bug or issue. If this is the case, it is important to check whether you are running the latest version of macOS and install any necessary updates.
To check whether there’s an update you need to install, follow the steps below:
- Click the Apple logo and choose App Store under System Preferences.
- Click the Updates tab.
- Install all updates, if there are any.
After installing all the updates, restart your Mac and check whether your RAM problem has been resolved.
Check Memory Usage via Activity Monitor
When your app freezes or your Mac seems to be slower than usual, the first thing you need to check is the Activity Monitor. This is a built-in tool that shows you how much memory is being used, which apps are using it, and how much memory each app or process is hogging. The Activity Monitor will also help you determine if a particular process or app is consuming memory resources more than it should.
When you access the Activity Monitor app, you’ll see complete information regarding each running process or app. You can also add extra data by adding columns on the window.
To launch Activity Monitor, go to Finder > Go > Utilities > Activity Monitor or type in activity monitor in Spotlight. In the Activity Monitor Window, you’ll see a list of processes along with tabs of information regarding those processes, namely CPU, Memory, Energy, Disk, and Network.
Click on the Memory tab to understand how your memory is actually being used by your apps and processes. At the bottom of the window, you’ll see a graph on Memory Pressure and information regarding Physical Memory, Memory Used, Cached Files , and Swap Used. On the rightmost side of the graph, you’ll see data for App Memory, Wired Memory, and Compressed.
The Memory Pressure graph shows how much pressure your computer’s RAM is currently under. Ideally, the graph should be green, which indicates low pressure for your memory. A yellow graph means that you are short of memory while a red graph indicates a critical situation for your RAM, at which point you need to free up some space as soon as possible.
Follow the instructions below to free up some of your RAM using Activity Monitor:
- Launch Activity Monitor and click on the Memory tab.
- Click on the Memory column to arrange the processes according to their memory usage. Make sure that the processes are sorted out from the highest to the lowest.
- If you think that an app is consuming more than its share of memory resources, you can easily kill the process by clicking on the Quit button. Take note, however, that this does not necessarily kill the app. If the process you killed is a webpage, it will just close and reload that page without closing the browser. But if you closed a specific app, you’ll usually see a “closed unexpectedly” warning.
Warning: Don’t close processes that you are not familiar with because they may be related to other important processes on your computer.
Close Unnecessary Apps
Some Mac users are guilty of clicking the close button and thinking that the app is already close d. Note, though, that clicking the close button only closes the window, not the app itself. More often than not, you’re left with several apps still open without you even knowing about it.
Even without looking at the Activity Monitor, you can see which apps are running just by looking at the Dock. If you see a dot below the icon of the app, it means that these apps are still open.
Here’s how to properly close an application and free up some of your memory:
- Right-click the app icon on the Dock.
- Select Quit from the right-click menu.
- Alternatively, you can also choose Quit from the app’s top menu.
Tidy Up Your Files
If you have the habit of saving everything on your Desktop and just leaving them there, then you might want to organize your stuff to lessen the stress on your computer. macOS treats every icon on the Desktop as an active window, so the more items you have on it, the bigger your memory consumption will be.
Delete all unnecessary files and get rid of your junk files using an app such as Mac repair app. You can also drag all of them into one folder to make your Desktop neat and tidy.
Delete Cache Files
Deleting cache files will help free up some of your memory, but this is not something a beginner should do. The Cache folder contains some system files that are important for your Mac to run properly, so you should know which files to delete and which ones to keep.
If you’re confident that you know what you’re doing, you can delete cache files by following these steps:
- Click Finder > Go > Go to Folder.
- Type in ~/Library/Caches/ in the dialog box.
- Delete the cache files that you don’t need in the folder, but make sure that you know what files you are deleting.
Clear Inactive Memory via Terminal
Another way to free up your computer’s memory is by purging it using the Terminal. To do this, open the Terminal and type in sudo purge. Hit Enter and type in the admin password. Next, wait as your Mac’s inactive memory is being deleted.
- Edit Your Finder Settings.
If you launch the Finder app and you see either All My Files or Recents, then you might want to change how your Finder app is configured because all the locations of the files shown in that window will be stored in RAM, therefore using up more resources. What you can do is show a specific folder so that only one location will appear.
To do this:
- Launch Finder and go to Preferences.
- Click the General tab.
- Under New Finder windows show , choose a specific folder such as Documents or Desktop.
- Close Finder and relaunch the app.
If you have multiple Finder windows open, you can either close those that you don’t need or merge them all together. To merge all open window, click Window from the top menu and click Merge All Windows. This may not save you a huge chunk of memory space, but it helps.
