After reading horror stories on this taking forever, I started looking into why and into ways to speed this up.Īnd what surprised me was that the system is 98% idle. Then when I looked again a while later it said it would take 'more than one day'.
It started out with saying it would take 3 hours. I also ensured that the system doesn't go to sleep. So, I turned it off in System Preferences. There is a reason for me (testing) to turn off FileVault encryption on the boot drive on my Mac running macOS High Sierra (long story, off topic).
