Re: Trying Big Sur from external boot drive question

I use and NVME M2 external boot drive on my 2017 27" iMac and the drive updated to Big Sur with no problems. One comment on updating to Big Sur, there have been quite a few comments on "black screens". I did get "black screens but simply walked away, only to come back and find a loading screen and everything was fine. I think some people may be getting impatient or panicking when this happens and then they interrupt the update process. It would be helpful if Apple provided a description of the update process.
