    So, the update downloaded just fine, screen went black and was beachballing for about 10 minutes. At that point, I decided to pull the plug and shut down. Now, after a PRAM reset, I get to the login screen, the bar fills up and nothing happens. I don't see a recovery partition at boot - any thoughts?

    Holding CMD+R on startup does nothing?

    Yeah try holding down Command-R. The Recovery partition doesn't always appear in the boot menu.

    In App Store in Recovery OS?

    If not in App Store, then can you share a photograph, or describe the context?

    Not sure what was going on, but I was able to repair the disk permissions using recovery mode, and at least boot into the system. Because the DP5 update itself had failed, nothing was able to load - Finder and Siri kept crashing, none of the system preferences panes were loading either. Luckily, file sharing was enabled, so I used another Mac to transfer the files I knew weren't backed up (latest TM backup was a 100+ days old). Once that was done, I restored using the old TM backup and re-downloaded Sierra.

    OK. Given the set of symptoms that you describe, it's possible that a prior installation was (or somehow became) corrupt.

    That's interesting. Can you recall whether (are you certain that) it was truly permissions that received attention? I ask because I don't expect to find attention to permissions in Disk Utility in Recovery OS 10.11 or later. More specifically, I wonder about an HFS Plus file system inconsistency.
