Two weeks ago, I upgraded from Catalina to Big Sur on my 2014 MacBook Pro.
Today, I tried to run Disk Utility from the Finder. It fails to load disks. It shows the “Loading disks” message, and a spinning wheel, but fails to load either the internal SSD or any of three external disks (one Toshiba SSD, two spinning disks).
I am not having any problems accessing any disks, or running applications, or copying, moving or saving to any disks. The disks all appear in Finder, and I can see all folders and files on them in Finder. The disks all mount, and I can click on the eject icon in Finder to successfully eject any of the external drives.
Is anyone else experiencing this Disk Utility issue on Big Sur? Any suggestions for a remedy?
