Hello,
Our machines can not pass Big Sur update in 11.1, the update stuck indefinitely on the "Preparing macOS Big Sur 11.1 Update..." .
Others with the problem? Is there a way to fix it?
Thank's

We saw the same issue the day 11.1 came out.
It worked fine the following day.
The problem still persists on my side on the macs enrolled in JAMF ..
Indeed the process com.apple.MobileSoftwareUpdate.UpdateBrainService high on CPU all the time when I try to pass the update. My only solution is to start and run the update in safe mode for the moment.
