I also had this happen on my late 2013 MBP 15, it stayed on black screen for hours. I had an external monitor attached, so I was curious if that was affecting the update. I unplugged the monitor and then reset the laptop. It took at couple attempts, but the update resumed and I'm running Big Sur with no issues. |
