macOS Recovery, also known as macOS Base System and formerly known as Mac Recovery Mode, is an option available to users of recent versions of macOS or OS X in case a problem renders their Mac unbootable.[1][2]

- Reinstall macOS on the startup volume.
- Safari, to browse Apple Support and get help online.
- Disk Utility, to repair or erase a drive.
Earlier versions of the mode included the following additional utilities:[7]

History
Mac Recovery Mode was first introduced in 2011 with Mac OS X 10.7 (Lion) and was stored in a hidden HFS Plus partition. The mode would bring up a window of options, titled "Mac OS X Utilities", later "OS X Utilties" and "macOS Utilities", before being replaced by a simpler untitled palette.[2][7] Starting with the introduction of APFS in macOS High Sierra (10.13) in 2017, the "Recovery HD" was stored in a hidden volume instead of a partition.[5]
