disk cleanup - Apple OS

To do disk cleanup on Mac:

A. For years, Mac computers did not come with utilities like Disk Cleanup and the newer Storage Sense found in Windows, but Apple added new tools in 2016 with the release of its macOS Sierra system. If your Mac is running at least that version of the system, go to the Apple Menu, select About This Mac and click the Storage tab.

On the Storage screen, you should see a graphic showing your drive’s available space. Click the Manage button on the right side of the box to get started. The resulting storage-management screen offers four ways to clear off old files: Store in iCloud, Optimize Storage, Empty Trash Automatically and Reduce Clutter.

As one might expect, the Store in iCloud option punts documents, photos and Messages off your Mac’s drive and into your iCloud online storage locker. While this does free up room on the computer, you may have to buy more iCloud storage space from Apple if you fill up your five gigabytes that come free with an iCloud account.
