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 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.
