Hello Tom, I tried to repair the macOS Catalina start up disk using disk utility. But when first time the first aid option failed then again run the first aid. Disk utility showed the overlapped extent allocation error. But I could not replace the damaged file. I did not have the backup, and I was to regain my system. I found some software for disk recovery like Stellar Data Recovery for Mac, DiskDrill Data Recovery and Pandora. I downloaded free version of stellar and disk drill. Luck by chance I recovered in first attempt by stellar.
Upgrading from 10.15 to 10.15.1 failed on my 2012 Mac mini. I solved this by downloading the complete 10.15.1 installer, and install it on an external disk (just to be safe). This install finished properly but running 10.15.1 on an external disk triggers the XprotectService running wild problem (reported elsewhere) that consumes most CPU resources and makes my mini very very slow. Repeatedly killing the XprotectService process makes it possibnle to get some basic things done nut not much more. I managed to migrate my data from the internal disk to the USB disk (took very very long due to the XprotectService problem), and then managed to install 10.15.1 competely on the internal disk using the installer. Running from the internal disk does not trigger the XProtectService problem, so I have been happy but waiting for 10.15.2 to fix this issue.

Broke the dual displays on my Late 2012 Mac Mini. The Thunderbolt-to-VGA adapter works. The USB-to-VGA is detected but the display is blank. Apple support has no clue. Rolled back to Mojave and everything is OK. Apple support is calling back next week after I restore Catalina from a Time Machine backup so they can download the logs for review.
This software was free, and it let you create both a restore image and recovery media as well as backup your data in case of any issues with your system. We recommended running this once you confirmed that you had the machine fully set up and working as you liked it, but before you added all of your data and software. Dell no longer supplies or distributes this application. Windows 10 made it unnecessary:
The TS-453D perfectly integrates NAS with mainstream cloud services. By deploying cloud storage gateways and enabling local caching on the NAS, you can seamlessly use the cloud for storage, backup, and data recovery with low-latency access, providing an innovative hybrid cloud experience.
