Erase your M1 Mac and reinstall macOS
Sometimes, you want to reset your M1 Mac after you've run into issues like Mac frequent crash or Mac can't startup. In such a situation, you need to boot into macOS Recovery mode and erase your disk first.
Take care that erasing the disk will make data loss. If you've backed up your Mac with Time Machine before, you can restore your Mac with Time Machine backup after disk erasure.
To erase the disk, you should:
- Select Disk Utility and click Continue.
- Choose the system volume (Labled "Macintosh HD" by default) on the left side of the Disk Utility window.
- Click the Erase feature you'll see the following hint:
Erasing "Macintosh HD" will permanently erase all data stored on it. You can't undo this action.
The system "Macintosh HD" is a member of a volume group, a set of volumes containing macOS and user data, including the data volume "Data". You may erase just the system volume or all the volumes in the group.
If you choose Erase Volume Group, it will erase all data include your personal data (Usually stored in the Macintosh HD-data volume) on your Mac. While select Erase, it will only erase the system-related data (data stored on the Macintosh HD volume).
Before selecting Erase Volume Group or Erase, set a name for the volume and select APFS as the file system of the volume.
After the disk has been erased, the next is to reinstall macOS.
However, if you erased your M1 Mac before updating to macOS Big Sur 11.0.1, the system reinstalling process may be prevented by an error message, which reads like "An error occurred while preparing the update. Failed to personalize the software update. Please try again." You can use the Apple Configurator 2 on the other Mac to revive or restore your M1 Mac.
macOS Recovery mode likes a troubleshooter when your Mac has problems. It offers you chances to fix your unbootable Mac with a series of recovery options. And since the M1 Mac recovery mode has made some changes, you'd better learn in advance for further use.
