Having finally bit the bullet and pulled the Upgrade trigger, I'm now running Big Sur 11.2.2 without issue....I did discover that one of my favorite "go-to" graphic user interface built-in utilities has been deprecated, however, with Big Sur. The Network Utility is no longer. All the functions remain available through the Terminal and the command line interface, but having access to those functions through a convenient GUI will be missed.
Thanks for the report. I did upgrade from V11.2 to V11.2.2 on my "test" external SSD, and it seems to be fine. However, I am waiting for V11.3, which should be out shortly, before I make the final move from Catalina. Things with Tech Tool Pro will need to be fine with V11.3, though. We'll see.
Still bummed out, though, that for Intel-based Macs, there is no newer version of SuperDuper!, like there is for Carbon Copy Cloner (CCC). If I do make the move to V11.3, I will need to purchase CCC (can use it free for the first 30 days).
