==History==
Drive Utility dates back to on January 4, 2001, before the first release of Mac OS X 10.0 (Cheetah). It initially consolidated the features of Disk First Aid and Drive Setup from classic Mac OS. The version included with Mac OS X 10.3 (Panther) incorporated the features of Disk Copy.
Version 15, which was included with OS X 10.11 (El Capitan), greatly streamlined the user interface, eliminating permissions repairs due to the introduction of System Integrity Protection (SIP).All you need to know about Disk Utility in El Capitan by John Harris, Remo Software. 2020-02-14. Version 16, which was included with macOS 10.13 (High Sierra), added support for APFS.
