However, the shut down problem still persisted. I started seeing the computer verifying some of the applications. There was an additional “Macintosh HD data”. After the installation, it has 6 volumes with three mounted. (5) Previous to erasing the volumes, the disk has 5 volumes with 2 mounted. (f) Use timemachine backup to restore data (d) Use disk utility to erase two volumes (“Macintosh HD data” first, and then “Macintosh HD”) (c) Use Command-R to get to MacOS utilities (I am already in 10.15.7) (4) I did a timemachine full backup on October 11 and called Apple Support on Oct 12, the Tech Support person walked me through the followings: That is supposed to be a Catalina feature. At this stage, the computer did not verify an application before opening it. The shut down problem continued and some applications would not respond. (3) I called Apple Support on September 30, and we reinstalled Catalina using Command-R. As long as the warning is absent, I can shut down normally. However, after some time, something will do something to the system so that if I run “First Aid” using Disk Utility, it will trigger a warning (“Spaceman main free count 218039846 dos not match sum of free counts 218126044”, the numbers change each time). What I noticed is that I would be able to shut down normally right after the reboot. After that, the computer would not shut down normally and would reboot after a “panic: watchdog time-out”.

(2) I called Apple Support and after some diagnostics, we decided to install Catalina using Option-Command-R without erasing any volumes. It took two minutes for a pull down menu to come down. Here is what I did and some observations. I have the same vintage Mac Mini with a 1 TB hard disk and had the same problem.
