After upgrade to 10.12.2 macbook pro has black screen

My Mac is still under AppleCare. I'll give them a call this morning and see what they say.

You apparently posted this thread twice. I saw the other one and replied as follows:

Same sequence of events here: Upgraded to 10.12.2 yesterday afternoon. Used computer the rest of the day, then went to bed, letting computer go to sleep on its own. This morning, shortly after 5:00AM, we had a power surge, so computer restarted on its own. I now have a blacks screen, with a perfectly operating pointer, but unable to see anything at all. Did the same steps as francesco238 above with no luck. Had a CCC backup, so tried that, but because it had backed up last night at 10:30, it had 10.12.2 on it and the same thing happened. Amazingly, the (Apple) screensaver is working after the usual 15 minute delay, but no sequence of clicks or movements of the cursor or keyboard will get rid of screensaver.

My computer is a late-2012 Mac Mini, with 16Gb RAM, OWC SSD startup drive, Mac 27" Cinema Display

Followup: Tried every little trick I could think of, including one involving Single user ode. MNothing worked. Am in process of restoring from Time Machine backup from yesterday morning.

Apple wasn't much help--he only recommended things that we have already done. I pointed him to this report and a second thread that appeared here in the last hour or so with the same problem. He said random problems occur with every system software update, so wait a day and try again... and he'd pass the report up the ladder...

I'm going to wait a while and watch these forums to see if the problem is widespread. Then I'll try the combo updater rather than using the updater from the App Store.

I'd have to run out of options before I start messing with the Terminal, but you may be more adventuresome than I am.

Did you try restarting in Single User mode (Command+S)?

I tried Single User mode--black screen after Apple logo and progress bar.

Like mathman47 above, I also saw the screensaver after 15 minutes of black. No response to keystrokes or mouse clicks...

Same problem here. New Mac Book Pro 13". A lot of problem to transfer from Time Machine especially that kind of applications that are running with parallel desktop.

This evening i have update Sierra then black screen. Now reinstalling Sierra.

During the past few years i notice that the quality and performance aren't anymore so high standard like in the past.

I hope that Apple back to focus more on the quality and reliability of products.

Regards

...still under AppleCare? How?

AppleCare adds an extra two years to the standard one year factory warranty. I still have a few months left...

Same issue here, I have a mac mini late 2012

I was able to boot once in safe mode, i successfully saw the login screen but after logging in with my user i found the black screen again

i would like to try from guest user, not sure if it will make any difference

Restoring from time machine i guess it would take a lot of time

What about reinstalling macOS from recovery? can i lose something?

after reinstalling macOS from recovery i still end up, after iCloud configuration, to a black screen

just typed my account password and hit enter and it logged me in to desktop

Had the same issue on my MacPro 2010.
