Mine came with 11.0 and for reasons already discussed elsewhere I manually installed 11.1 from a USB installer I made.
My M1 MBP never saw 11.0.1
My magic mouse 2 behaves itself and I've had no wifi problems so far.
Interestingly, whilst my magic mouse was charging I connected my Logitech USB mouse and after about 5 to 10 minutes it became jerky and wouldn't click on anything. It also stopped moving from time to time.
Probably more of a Big Sur driver problem though.
Last night I also had a crash but it was probably my fault. I'm waiting for Caldigit to get back to me.
When it restarted it showed a report that a kernel panic had occurred.
I'd had a USB HDD connected through the Caldigit TS3+ for my TM backup.
When that finished I ejected the drive as normal and when it disappeared from the desktop I pulled the USB plug out of the TS3+ and the MBP immediately crashed/rebooted.
I'm wondering if I should have pulled the power plug from the HDD before I unplugged the USB plug.
If that's the case I could see why it could cause a problem for the TS3+ but not the Mac.
I await their instructions
