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

Falguni: one of the early steps I took was to boot in Recovery Mode and reinstall OS Sierra (10.12.2) but that didn't resolve the issue.

Only by restoring from a Time Machine backup (at level 10.12.1) is my Mac apparently stable again.

After reinstalling the os in repair mode the black screen is still an issue.

i did, however, type my password and was able to get to finder.

Apple could do the courtesy of some type of release. This is no small thing to put your customers through.

Final, summa, the issue is not resolved

😟

For me to resolve the issue of black screen I had to reinstall everything. Meaning, lose all the data I initially had in my computer

I allowed the 10.12.2 update to install itself this morning - touch wood, everything seems to be in order.

Let me begin by saying that I'm extremely dismayed and horrified at the quality of updates to the Mac OSX Apple releases nowadays. As soon as I updated to Sierra major pain started in the back of my neck and it hasn't left since. Now it's been months. I sincerely hope the ghost of Steve Jobs comes back to kick some major @ss! He would be very displeased at the state of affairs.

There are north of major 32 bugs I discovered and that's just me. Things just stopped working. Really Apple? This is called an "upgrade" in you book?

After updating to 10.12.2 hoping some of the annoying issues would be resolved with the OS I was also faced with the screen of black death. I have 2 displays plugged into my Macbook Pro Retina (mid-2015) via thunderbolt plugs and an external keyboard via USB.

After much experimentation and employing the good ol' process of elimination—and yes resetting the SMC and PRAM and booting up with safe mode—I discovered that on my end it was a USB issue. (It may be something else on your side.) As soon as I unplugged the USB cable which runs into a 4-way USB hub and restarted, I got the Apple logo and a normal startup.

Not sure if this will help you but go through the same process if you have things plugged into your laptop.

Do you have Duet Display installed by any chance?
