MacOS Big Sur updates freezes 11.2.1 and 11.2.2 - No progress
It is impossible on my MacBook Pro 2019 to update MacOs Big Sur to the new releases from January/February 2021. I can download the 3+ Giga update, but than install freezes during "preparing mac OS Big Sur..." after a progress of approx 75% (10 minutes remaining).
This happens with both updates 11.2.1. and 11.2.2.
I have about 300Gb free hard disk space, and attempted several times, including after re-starting the OS
I' waited for long time, even 2 hours, but "preparation of mac OS" doesn't progresses.
I had installed updates before w/o any issue, including the upgrade to Big Sur.
Any proposed troubleshooting idea or solution from the community?
MacBook Pro 15″, macOS 10.14
