[Solved] The given APFS volume is already encrypting or decrypting
After updating to macOS High Sierra on MacBook Pro, when I try to convert the Macintosh HD to APFS (Encrypted), the encryption process is permanently paused at 10.0% for no reason then the system crashes. Then I boot into Recovery Mode, I can unlock the volume using Terminal but when I try to decrypt I got the following message:
"Error starting background decryption of APFS volume: The given APFS volume is already encrypting or decrypting (-69573)"
It has been a long time that Apple finally has released a new default file system called APFS. APFS comes with many new features. The most attracting one is native encryption support. Unlike the full-disk version of FileVault encryption, APFS supports file system encryption which can be used to encrypt user data, metadata and individual piece of files.
Sometimes however, when attempting to decrypt an APFS encrypted volume in Terminal, you may receive error messages like "the given APFS Volume is already encrypting or decrypting (-69573)" or "APFS volume decryption failed to begin". It's so desperate especially if you have important files on the APFS encrypted volume. Unable to unlock an APFS volume and worry about data loss on it?
