Update to macOS Big Sur 11.1 from 11.0.1 fails

I'm having trouble updating from macOS Big Sur 11.0.1 to 11.1? I've had issues on both my 2013 Mac Pro and my 2016 13" MacBook Pro. In both cases, the upgrade appears to progress normally (you get progress bars during the reboot cycle, and you get a post-upgrade setup screen after reboot--which basically just requires re-entry of the iCloud password), but after the boot completes there is a kernel crash reporter, About This Mac still shows 11.0.1, and System Preferences still shows the 11. update as being available.

Both computers had a "clean" install to 11.0 when it was released (drive reformat, no time machine restore).

On my Mac Pro, the upgrade was successful on the second attempt. On the MacBook, I've had three failed attempts, all as described above.

Anybody else seeing this? Any suggestions?

Boot into Safe Mode by booting with the Shift key held down and try the update from there.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following; =

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts

• Deletes font caches, kernel cache, and other system cache files
