How does CleanMyMac 3 help speed up your Mac?

If you read through what Clean My Mac 3 did above, you would have probably got the idea that the app does a lot of cleaning. How does cleaning up disk space help improve your Mac’s performance.

It all boils down to virtual memory in the form of free disk space on your OS X partition. You see, when your Mac’s processor runs out of RAM, it dips into free disk space to use as virtual memory. This doesn’t happen all the time but it does happen from time to time.

In other words, when you are doing something memory intensive, like maybe video or audio editing or have a lot of multi-tasking going on, your RAM usage % is going to be pretty high.

If your Mac tried to use your RAM to a 100% capacity, it will result in that dreaded freeze up, where nothing happens when you press a key or move a mouse. Before your RAM chokes at 100%, your Mac’s processor will start using free disk space on your OS X partition as virtual memory.

This will work fine, assuming of course that your OS X Partition has enough free disk space. As a general rule of thumb, experts will recommend that you have at least 15% of disk space on your OS X Partition as free disk space.

We actually recommend that you keep 40% free. Here are several simple ways to clean up your OS X parition, particularly if it is on a SSD.

Hence, coming  back to Clean My Mac 3, by freeing up disk space on your precious OS X partition, it helps your Mac’s processor cope with extra memory requirements when required, thereby giving you better performance levels.

Besides freeing up OS X performance, Clean My Mac 2 can uninstall programs or disable browser extensions that you might never need, freeing up precious amounts of RAM that will then in turn allow to enjoy a faster Mac.

While the uninstalling and disabling of apps and extensions is not automatic, Clean My Mac 2 makes it very easy for you, populating a list of potential apps and extensions that you can easily disable to enjoy a faster Mac.
