How to Free up Storage on Mac (8 Easy Ways)

Part 1. What is RAM?

Before getting started, let's first figure out what is RAM and its importance to your Mac.

RAM stands for Random Access Memory. The computer would divide such a part for keeping temporary files generated while it's performing daily. It enables a computer to carry files between the computer and the system drive for making sure the computer runs properly. Generally, RAM memory will be measured in GB. Most Mac computers have 8GB or 16GB of RAM storage. Compared to the hard drive, RAM memory is much smaller.

RAM VS Hard Drive

Okay, when we also refer to the hard drive, what's the difference between them?

The hard drive is the place where you will keep all your documents and files, and it can be divided into separate drives. However, RAM is not able to be selected for saving any document, app, or file, because it is a built-in drive to transfer and allocate system files for the computer to work normally. RAM is considered as the workspace of a computer, and it would directly transfer the files it needs to work with from the computer drive to the workspace for running. In other words, if your computer has much RAM memory, it can handle more tasks at the same time.

How to Check RAM Usage on Mac

Checking the storage space of a Mac is simple, but you may be not familiar with it. Actually, to check RAM usage on Mac, you need to go to Applications for entering Activity Monitor in its search bar for access. You can also press F4 to quickly place the cursor in the search bar for typing. Then a window will pop up for showing you the memory pressure of your Mac. Here are what the different memories mean:

App memory: the space used for apps performance

Wired memory: reserved by apps, unable to be freed up

Compressed: inactive, can be used by other apps

Swap used: used by macOS to function

Cached files: can be really used to save cache data

However, rather than checking the figures, it would be more important for you to measure the availability of your RAM memory by checking the color grasp in Memory Pressure. When it shows a yellow or even red color, that means you really have to free up RAM memory for bringing Mac back to normal performance again.

What Happens if Your Mac is Short of Memory

When your Mac is lacking in RAM memory, it may face such issues:
