Cleaning your Mac is generally a healthy practice but since we’re about to back your Mac up, it’s worthwhile to get rid of system junk first. After we’ve cleaned your Mac, you’ll end up with a refreshed system ready for a Time Machine backup.

Install the app and click on System Junk to perform the scan.
