How to use macOS RecoveryIf your Mac doesn't start up or won't update the latest macOS, don't worry! macOS Recovery can help.
Your Mac has a built-in repair service that makes it possible for you to recover your Mac's operating system if something should go wrong. It's called macOS Recovery and it makes it possible for you to:
Install the most recent operating system that was installed on your Mac
Upgrade macOS to the most current, compatible version
Install the operating system that came with your Mac (or the version closest to it that's still available).
It also lets you repair or erase a disk if something is wrong with your built-in hard drive and makes it possible for you to get online Apple support, even if the rest of the computer is borked.
