How do I do that without losing any personal files?Same problem on MBP 15" 2.8 GHz Intel Core i7.
I had to re-install 10.12.1.
how long you waited? I got blank screen for about 5 minutes and then it continued the installation.
How long are we talking?Yes, here too. I left and started supper, came back, still black. Pressed the space bar, entered my password and viola. You guys need to be more patient.

Maybe I wasn't clear. It finished the installation. Desktop was showing. I restarted for some reason and by the time the apple logo and loading bar was gone it was all black.
If I wait a couple of days will I be able to reinstall with a newer fixed version through "internet recovery" ?
I don't think I've ever gone through an Apple OS update, or iOS update for that matter, without major issues. Tim Cook needs a smack upside the head.
I've been an Apple user for a few years now. I wish I had a better experience, I really do.I've been a Mac user since 1986, yes that's 30+ years. In all that time, I've only had one OS update go awry. As I recall it was 4 or 5 years ago. Can't remember the update! It was on my MBA, not my cMP.

I had previously the beta versions which installed that FW Update.The loud single note means it installed a firmware update.

Had the same issue. This worked for me:

Guess something in the auto login plist was corrupt or just wrong.
Edit: Solved.
Completely black screen after booting up with 10.12.2. I can adjust the volume and brightness and move the mouse around.

Thanks Apple..
