Question: Endless spinning during upgrade to High Sierra

Since last Saturday afternoon, the High Sierra upgrade process stopped at black screen with an endless spinner.

It lasts over 55 hours. And the spinner will jump every 3~5 seconds.

I'm not sure I should restart to see what will happened.

My friend told me that's the problem about FileVault.

Any one got the same problem?

Turning off FileVault shouldn't damage your data although there is always that risk. Do you maintain external backups? Understand that disabling FileVault takes quite some time and will require some amount of free space on the encrypted drive.
