How to Revive and Restore M1 Macs – MacBook Air, Pro, and Mac mini
What is an M1 Mac Revive?
Here’s how Apple describes when to “revive” an M1 Mac and what it does:
In very rare cases, e.g. For example, if there is a power outage during a MacOS upgrade, a Mac may become unresponsive and the firmware needs to be revitalized. A Revive updates the firmware and updates recoveryOS to the latest version. No changes are made to the startup volume, the user’s data volume, or any other volume when it is revived.
However, be aware that if you need to reinstall macOS after a revival, your drive will be erased.
What is an M1 Mac recovery?
A restore will erase your Mac’s drive, but also restore the firmware, update recoveryOS to the latest version, and reinstall the latest version of macOS. Hence, you want your data to be backed up.
Have you already tried reinstalling macOS?
If you can start your M1 Mac with macOS Recovery, you may be able to reinstall macOS without reactivating it or performing a full recovery that requires both a second Mac and Apple Configurator 2. This will erase your drive.
- With the Mac off, press and hold the power button until you see “Load startup options.”
- Select options and click Next
- Enter your password if necessary
- Now select Reinstall macOS and click Next and follow the instructions
