Un encrypting a 2TB drive with Mohave
I am configuring a new hard drive for time machine. Encrypting was taking so long I decided to go without. I entered my PW as required to unencrypt. But then comes the error message:
"Unable to modify a FileVault context."
Is it possible to turn encryption off? Or does the drive need to be completely encrypted before encryption is turned off?
ps: this is a late 2014 Mac Mini, which was not a choice on the menu.
Mac mini 2018 or later
