APFS preboot volume error during macOS reinstallation
Hello community,
I’m having a problem with erasing the APPLE SSD Disk after trying to reinstall macOS and it saying “could not create APFS preboot volume”. When erasing the Disk, it says:
Unmounting disk
Couldn’t open device.
Operation failed.
Then I tried to partition it with Mac OS Extended (Journaled) with it named Macintosh HD and it says:
The volume “Recovery” on disk1s3 couldn’t be unmounted because it is in use by process 0 (kernel).
Couldn’t unmount disk.
I have tried loads of videos on YouTube. Using terminal commands…etc.
