Persistent Update drive icon on desktop since latest Monterey update
My box is a new M1 MacBook Pro (16-inch, 2021) with macOS 12.1
SSIA. A drive partition icon called update keeps showing up on the desktop even after ejecting it. When it is ejected, it returns in the next 1-2 hrs. The contents are a locked directory named "Controller", an empty folder named "Firmware", and two files - one file named "last_update_result.plist" and the other called "restore.log". Review of the log file makes me think this is a remnant from the update that did not get cleaned up. These files and folder dates are from back in November and December.
The question then is: how do I get rid of this short of data backup and fresh install of 12.1?
Interestingly, I have found several hidden volumes mounted including: Hardware, iSCPreboot, XART and even more interestingly a volume called Update that is separate from the one referenced above that contains the same folders and files listed above, but also a plethora of others. The files listed above exist there as well, but are dated today rather than Nov/Dec of last year. More evidence that the persistent desktop volume is some sort of orphaned remnant.
Ant thoughts would be welcomed.
