The macOS Big Sur update has been causing some older MacBook Pros to get stuck on a black screen during installation, with no way that users can find to fix it. The issue seems to be most common on late-2013 and mid-2014 models of the 13-inch MacBook Pro. Owners of other Macs have reported Big Sur installation issues, too — and some say they’ve been able to fix those issues — but those two models of MacBook Pro seem to be having the most severe problems for now.
The issues were spotted by MacRumors, which saw complaints of frozen laptops in its forums, on Reddit, and on Apple’s support site. There’s no clear indication of what could be causing the problem, and simple ways of fixing it — like resetting NVRAM or booting in safe mode —…tech, The Verge
