If your Mac has slowed down it's possible that your RAM is being used to the max. Here's how to free up memory on a Mac (or how to free up RAM), including ways to reduce Mac RAM usage without.
- Upgrade your iMac RAM for 63% less than factory costs and get up to 128GB of memory in select iMac models. Includes a lifetime memory warranty.
- Download more RAM for free and instantly from our website. Free upgrade 1GB RAM - 2GB RAM - 4GB RAM - 8GB RAM - 16GB RAM.
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?
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 OS X 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.
El Capitan OS X
- 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. We highly recommend CleanMyMac X, which will not only clean and speed up your Mac, it also has a RAM monitoring tool called Menu App.
Simply click on the Memory Monitor tab for a clear overview of your Mac’s memory usage. The tool will also enable you to free up memory by closing down unnecessary applications, which will become really helpful when your system is slowing to a crawl.
CleanMyMac X is a free 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.
How to upgrade RAM on an iMac
