The simplest answer to the question: how much RAM do I need for my Mac is ‘as much as possible.' You can never have too much RAM, whereas having too little can seriously affect the performance of your Mac. Sadly, however, it's not quite as simple as that. Adding extra RAM, whether you do it when you buy your new Mac or you add it later, costs money, quite a lot of money. So the question of how much RAM to put in a new Mac is comes down to the balance between affordability and the additional benefit you'll get from more RAM.
Why upgrade Mac RAM?
It used to be the case that adding more RAM would improve the performance of your Mac in almost every task. But computers have moved on since then. Better memory management, faster storage for caching files that can't be stored in RAM, and blazing fast graphics processing units (GPUs) with their own dedicated RAM mean that the load on your main Mac RAM is less than it used to be.
Much of the work in generating frames for games, for example, is done by the GPU and its RAM. However, if you work with large images (bigger than, say, 100MB) or with huge databases or monster-sized spreadsheets, more RAM will be a huge benefit.
How to check your Mac's RAM usage
The quickest way to identify whether you need more memory is to check your Mac's RAM usage.
One way to do that is to use the Manu App in CleanMyMac X. This feature will show you immediately how much free RAM you have and allows you to free up memory at the click of a button. It's the easiest way to monitor and free up RAM. So, download the app (for free) and monitor your memory usage.
Alternatively, you can check the RAM usage manually:
- Go to your Applications folder.
- Open the Utilities folder and launch Activity Monitor.
- Click the Memory tab at the top and look at the Memory Pressure graph at the bottom of the screen.
- To the right of the graph, you'll see a table. In that table, Physical Memory is the amount of RAM installed on your Mac.
Keep that window open while you work and check it now and again. If the graph stays green, there's nothing to worry about and you don't need more memory. If it's green and yellow, there's some pressure on your Mac's RAM but it's ok. If the graph is mostly red, however, it's under serious pressure and your Mac's startup drive is being used to store data that should be in RAM. This will slow down your Mac.
Just because the graph is in the red doesn't mean you need to rush out and buy more RAM (assuming you have a Mac that can be upgraded), however. Closing browser tabs you're not using will help, too. And you can free up memory by closing applications you're not using or by logging out of accounts that aren't in use, if you're signed into more than one account.
To find out which apps, processes and browser tabs are using up the most RAM, click the down arrow at the top of the Memory column in Activity Monitor. That will order processes by how much RAM they're using, allowing you to easily see who the culprits are. If you see any apps or web pages that are using lots of RAM and you don't need, close them.
There are also third-party utilities that can report memory usage and ‘clean' RAM when you close applications, so that the memory is freed up for use by other applications.
How can I upgrade Mac RAM?
Some Macs can be upgraded and some can't. If you've bought a MacBook, MacBook Pro or MacBook Air in the last five years or so, you won't be able to upgrade the memory in it. If you have an iMac, you may be able to perform a Mac RAM upgrade, depending on when it was made and whether it has free slots. You can find a complete list of which iMacs can be upgraded here.
The iMac Pro's memory can only be upgraded by Apple or an Authorised Service Provider. Both the Mac Pro and Mac mini can be upgraded.
How much RAM do I actually need?
So, after all that: how much RAM should you have fitted in a new Mac? For most users, 8GB is fine. You'll be able to quite comfortably work on documents, edit photos and video and surf the web without any problems.
If you work on very large image files, databases, or spreadsheets, or if you really need to have lots of applications open at the same time, you might consider upgrading to 16GB. But you'd need to weigh the cost of the extra RAM against the benefit you'd notice.
What else can I do to improve my Mac's performance?
The one and only reason for adding more RAM is to make your Mac run faster and more smoothly. However, there are other ways you can do this. Swapping a hard drive for an SSD, for example, won't just boost startup times, but because macOS uses the startup drive to cache files, it will improve performance too.
Also, freeing up space on your startup drive will help, particularly getting rid of files you don't need and that clog up your system. The best way to do that is to use a tool like CleanMyMac X. CleanMyMac scans your Mac for files it thinks you no longer need. These include system junk, Photos files that can be safely removed, and Mail attachments that can be re-downloaded if you ever need them again, and much more. By the way, the app is free to download, so give it a try!
As you can see, deciding how much RAM you need for your Mac isn't straightforward. There are lots of things to consider. However, adding more RAM isn't the guaranteed performance boost it used to be. For most people, the base 8GB that ships with current Macs is enough. If you do think your Mac could do with a performance boost, try the techniques described above before you rush out and buy more 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.
