com.apple.DiskManagement.disenter error 49229
I have the same problem as https://discussions.apple.com/thread/251298444
That ticket has 138 "I have this question too".
But nevertheless it was closed with nothing other than "format your drive, have a great day"....
I had this issue after dd-ing hard a partition from another mac. Others apparently when trying to mount a system partition while setting up the system.
Is dd'ing a hard drive not acceptable anymore to Apple? How then do you duplicate a (possibly bootable) partition to another machine
