    CleanMate. This is the app i am using for clearing system data on mac. You can get a lot of free spaces by removing the system junk files, temporary files and caches one. It is just done in 1-click.

Safe Boot is a built-in macOS startup mode that automatically performs system maintenance, including clearing system data on Mac.

How to do it:

1. Shut down your Mac completely

2. Turn it on and immediately press and hold the Shift key

3. Release the Shift key when you see the login window

4. Log in normally (you may need to log in twice)

5. Restart your Mac normally (don't hold any keys)

 

What it does for clear system data on Mac:

* Automatically clears system cache files

* Verifies your startup disk

* Deletes temporary files and some system logs
