Have you ever heard about Clean My Mac 3? Should you buy it and use to clean up your Mac?

Well, you will find out soon enough after reading this Clean My Mac 3 review – from me.

The story is I’m using a MacBook Pro 15-inch Mid 2010 and still don’t have any plans to upgrade to a higher model.

Last month, when I turn my Mac on, there was a warning appeared on my screen. It said: Your startup disk is full, and suggested me to delete some files to make more space available on the disk. At that moment, I ignored the warning and keep using my Mac as I often do.

However, it seems my Mac ran slower than before. There was a bit of delay when I open a new application. It was not open immediately as it often. Instead, when I click on an app to use, it only opens after five seconds.

I thought this delay might be related to the previous warning that told me my startup disk was full. I did some searches on Google and asked a few experts about this issue. The answers I got from both places confirmed what I thought. Therefore, if I want my Mac back to normal, I have to remove some files and make more storage space on my startup disk.

But how?

What Is Clean My Mac 3?

Alize, one of my friends, told me if I want to fix this issue, as well as clean up my disk, I have to download & install Clean My Mac 3. Then use this cleanup app to do so.

She said it is a good and must-have app for Mac OS, which helps me to clean up my Mac from temporary files, duplicate files, or large files that taken a lot of storage spaces – as well as maintain the best performance for Mac computer.

I don’t know whether she exaggerates, but there is nothing to lose by trying the app.

I have downloaded Clean My Mac 3 and installed it on my Mac to try. It didn’t ask me to buy a license in order to use. However, it seems without a premium license you only can remove up to 500MB of files.

I ran a test. The app found around 3GB of temporary files that I could remove to gain more storage space on my startup disk. It also showed around 50GB of large files, which I could remove or move to an external hard drive to have more storage space.
