Big Sur 11.1 update not installing
I have a 2019 16" MacBook Pro (Big Sur 11.0.1) , and I have been trying to install the updated OS (11.1) for several days with no success. It downloads the package, but then sits in "Preparing MacOS Big Sur 11.1 Update, 15 mins. remaining".... forever. So far I've tried: booting into Safe Mode, resetting the SMC, resetting the PRAM, and booting into Internet Recovery Mode (scary - exited without continuing). Other people are having the same issue. Some of them have solved it with Safe Mode, but that did not work for me. Yes, I have a Time Machine backup from yesterday. Thanks for any suggestions.
MacBook Pro 16″, macOS 11.0
