High Sierra could not turn on FileVault after turning it off

Hi,


Yeasterday I turned off my FileVault. And now I want to turn it on again but I am getting this error:


"Authentication server refused operation because the current credentials are not authorized for the requested operation."

I am running MacBook Pro (Retina, 13-inch, Early 2015) on High Sierra 10.13


Thanks,

Kristian

I was having the same issue and done a bit of digging.

I found that iCloud was listed as an encrypted user so I signed out of iCloud on my Mac, and then turned FileVault back on the usual way, and it created a recovery key without any issues and then began the encryption process.


Let us know how you go 🙂
