macOS Monterey on a 2017 4k Intel iMac.
A week ago I turned FileVault on by mistake, so after it finished encrypting the drive I went straight to decrypt it.
Then I assume that near the end of the decryption, it went auto update and rebooted itself.
Now I can’t get into system. I’m now into a dead loop of
Reboot->Enter password->"Your computer has restarted because of a problem"->Reboot.
So I’m now in Recovery Mode.
Things I have checked (using Terminal):
- The drive is shown in Disk Utility as APFS(Encrypted), can be mounted and can read and write
diskutil apfs list: The drive
disk4s1(Macintosh HD – Data),
Decryption progress: 99.0% (Paused) (Unlocked),
diskutil cs list:
No CoreStorage logical volume groups found
diskutil apfs disableFileVault disk4s1 -user F0A57C09-753C-46BB-AD66-EC07CBF03DEB:
Error starting decryption of APFS Volume: The given APFS Volume is already encrypting or decrypting (-69573)
diskutil apfs unlockVolume disk4s1:
The APFS Volume disk4s1 is already unlocked (mounted)
/usr/libexec/corestoraged: Running or sleeping.
diskutil apfs liststill shown as
 The UUID is from
diskutil apfs listUsers disk4s1.
Now I see it’s stuck in 99.0%, is there a command to continue the decryption progress?
Or the worst, is the only way to save my data is to copy all files to an external drive and do a wipe?
