Disk Diet digs into Mac files you may not need and frees up a lot of storage; I’m talking about gigabytes of storage the first time you use it. Run the app and take a look at the space you reclaim.

Review from Noodle Mac

Once the app has done its magic, a simple click immediately erases all the dead weight, leaving you with a lighter (and probably faster) system.
