I was going to upgrade to new macOS Sierra on my MacBook Air but there's a FileVault process that is encrypting all the files that doesn't allow the installation of the new OS. In the window appears a message that says FileVault encrypting and a blue thermometer under which there's written counting the remaining time that keeps going back and forth.
Is there someone that can help me to solve this problem?
If I try to disable FileVault, it says that I can disable once encryption process is ended.
I'm upgrading from OS X El Capitain version 10.11.6. When I try to stop FileVault it says I can't disable because the encryption process in still ongoing.
P.S. I don't have an engineering background, so please suggest actions what doesn't involve manipulation with code or similar. Thanks a lot!
It's really an interesting system: it's 2 days I don't switch off the pc hoping that the coding process finishes and it's still calculating the remaining time.....
