- Buying Memory For Your Mac If you want to upgrade the memory in your older Mac, you can find the information you need on the Apple website. Apple maintains specific pages for different types of Macs. You can find out what type of memory you need to buy and how to install it.
- The 2020 MacBook Air makes the storage question a little easier, as it now starts off at 256GB. That's more than enough storage for the average computer user and likely enough for most professional work. You can purchase up to 2TB with the Air.
A mainstream desktop computer will usually come with more than 4GB PC RAM. If you tend to run multiple apps at the same time or edit large digital media files with photo editing software, look for 8GB RAM or more. You can also find computers that allow you to expand RAM, if you think you might need more computer memory later.
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. How to change fingerprint on macbook pro.
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.

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
- Shut down your iMac and unplug everything.
- Place iMac face down, ensuring the screen is protected from anything that could scratch it.
- Unscrew, counterclockwise, the RAM panel in the centre until it pops out.
- Expose ribbon tab over RAM and pull on it to release RAM module.
- Use your fingers to remove the RAM entirely.
- Line up the new RAM with the now empty slot and push it in until it clicks into place.
- Screw the RAM panel cover back on.
- Re-connect everything, turn your iMac back on and go to About This Mac to confirm new RAM installed.
How to upgrade RAM on a Macbook Pro
- Turn your Macbook off.
- Turn your Macbook upside down and pop the latch on the back to remove the plate.
- Use tiny phillips head screwdriver to unscrew the larger back plate.
- Note - one screw will be a lot smaller than the others. Remember where it goes.
- Touch metal to ground yourself before touching the RAM.
- The RAM is to the left or right of centre. Pull apart the latches on each side of it and the RAM will pop up.
- Slide the RAM out.
- Slide the new RAM into the slot and push it down till it clicks into place.
- Put the large backplate back on and screw it into place.
- Screw the smaller backplate back into place.
- Turn your Macbook on and and go to About This Mac to confirm new RAM installed.
How to upgrade RAM on a Mac Mini
Due to the form factor of the Mac Mini, it is one of the more challenging devices to upgrade. We recommend getting help from professionals or someone that has experience upgrading Mac Mini RAM.
The final word on Mac RAM upgrades
In this guide we showed you how to identify high memory usage on your Mac using OS X and the ever-useful CleanMyMac X. We then outlined the steps to determine what RAM your Mac has installed, whether it can be upgraded, how to purchase new memory for your Mac and finally how to install your new RAM into your Mac.
Once your new RAM is installed, depending on how much you were able to add, you should see a considerable boost to your Mac performance.
You will also gain a boost to your social status, as now you can confidently boast, 'I know how to upgrade my Mac memory'.

When your computer is running a bit slowly, how can you tell if getting more memory will help?
If you run out of free memory then your computer will be forced to use some of your hard disk as memory, which is VERY SLOW because hard drives are much slower to access than your computer's RAM. It's not just a matter of saying ‘8 GB' is enough because the amount of RAM you need will vary according to your Mac model and the programs you use. Here's how to check if you have enough RAM.
How to check your Memory on a Mac
With El Capitan Apple have introduced a very simple graph based on colours to let you know if you have enough RAM or not. Do this during the middle of using your computer for what you normally use it for. Don't do this as soon as you start your computer as this won't give a good indication of your normal usage. Better still, check it at various times over a few days.
- Go to your Applications/Utilities folder. (Click on your desktop so that the finder is active then hold down Apple-Shift-U, this will open your ‘utilities folder.)
- Open ‘Activity Monitor' – it will probably be the top-most application in the Utilities Folder.
- Press Apple-1 to make sure that the main window of Utility Monitor is open.
- Click on the ‘System Memory' tab at the bottom of the window. This will display a little graph with the memory pressure. It will look something like this:
If there is any red in the memory pressure you need more RAM. Red means your performance is taking a hit because your computer needs to use the disk drive for memory.
If the memory pressure is green you have enough memory (like the screenshot above).
If the memory pressure is yellow it may be worth monitoring over a few days to see if it goes into the red.

Checking your memory on older versions of Mac OS
On older versions of Mac OS the display looks more like this:
There are two important items to take note of ‘Free:' and ‘Page outs:'
Free tells you how much free memory you currently have available to use – the higher the better. If you have no free memory you should get more RAM.
A Page out means your computer has run out of memory and had to use some of the Hard Disk instead of RAM. (This is the equivalent of your brain being too full so you have to write your thoughts down on paper to free up some head space) This DRAMATICALLY slows down your computer.
Tip: Page outs occur when your Mac has to write information from RAM to the hard drive (because RAM is full). Adding more RAM may reduce page outs.
Some Examples:
Ia writer 5 2 – professional writing suite software. Here's a mac with plenty of RAM (12G) – lots of Free RAM (green) and zero Page outs.
Here's a mac with just enough RAM (8G) – a relatively little Page out Count (339MB) and some free memory (green).
Here's a Mac that needs more RAM (it only has 640M!) – note the High Page Out Count (1010524) even though it currently has some ‘free' RAM.
This Mac definitely needs some more RAM! Practically no free memory AND High Page-out Count. (1GB!) Performance will be suffering badly. I would add at least another 4G Ram, maybe 8G more to bring it up to 12G.
In OSX Leopard rather than giving a ‘count' of page in and page outs, it gives a size in GB of the amount of RAM that has been paged in or out. The numbers are smaller but the same principles apply.
In OSX Lion there is a new entry called ‘Swap Used'. (See the last picture above). This is a count of how much Disk Space your computer is using as RAM and it's a good rough estimate of the minimum amount of extra RAM you need. Eg If your Swap used is 4G then get AT LEAST 4G more RAM.

Where to buy more RAM.
You can't buy any RAM. It needs to be Apple compatible. It's worth getting good quality RAM to avoid problems. Currently my 2 favourite places to buy RAM are Crucial.com or OWC Computing. My Mac mini has 16GB of Crucial RAM in it at the moment. I'm in Australia and it usually arrives in about a week. OWC might be the better option if you live in the USA.
Crucial
They have a memory lookup tool for all computers where you choose your model and it shows you exactly what memory you need. The memory chooser tool looks like this:
First choose ‘Apple' where it says ‘Choose Manufacturer'
Secondly select your mac when it says ‘select product line' (e.g. iMac or Macbook etc)
Finally select the exact model (e.g. Early 2011 i7 27″ iMac')
It will then show you the options you can buy.
OWC – Macsales
Another reliable source of good Mac RAM is Other World Computing, also called macsales.com.
Why RAM affects your computer's speed.
RAM in your computer is like the paper sitting on your desk. The information is easy and fast to access. Your Hard Disk is more like a filing cabinet, it takes a bit longer to retrieve information.
When your desk gets too cluttered you need to spend some time moving things in and out of the filing cabinet, which slows things down.
You don't need to be able to store everything in your computers memory, it's good to have a hard disk, but if you don't have enough memory then your computer will need to access your hard disk too much and this can slow things down.
To quote from Apple:
Moving data from physical memory to disk is called paging out (or swapping out); moving data from disk to physical memory is called paging in (or swapping in)… Extended periods of paging activity reduce performance significantly; such activity is sometimes called disk thrashing.
