iFrodo Posted November 13, 2020 Share Posted November 13, 2020 (edited) I've had FileVault 2 enabled for some time now, and the installation of BigSur did go well. But after first reboot, I observed that the FileVault 2 password screen doesn't fully load, I only see the user icon and name and the mouse pointer, no background image, no text field to type the password. Anyone have had this issue before ? Is it possible to solve it ? Can I disable FileVault from recovery ?

iFrodo Posted November 13, 2020 Author Share Posted November 13, 2020 (edited) I found the way to decrypt the volume using command line (Terminal) on Recovery: - List volumes: diskutil apfs list => Find the volume(s) having "FileVault: YES" - Then list cryptousers : diskutil apfs listcryptousers /dev/diskXsY => Take the UUID (hexadecimal string seperated by dashes) of the "Local Open Directory User" - Finally decrypt the volume by typing: diskutil apfs descrypt /dev/diskXsY -user UserUUID -passphrase YourPassPhrase This will launch the decryption in the background, you can follow the progress by executing: diskutil apfs list => Look at "Decryption progress" value. Once fully decrypted, you can reboot normally, macOS will start without FileVault.
