I'm on a NcMP 7,1. I upgraded my startup disk to Ventura and when done, got to the desktop and the menu bar was pretty much empty. So I restarted. About ¼ of the way on the progress bar, I got a circle with a diagonal line through it and an apple web address below that ended in "startup". Everything stopped. I rebooted into startup manager and chose my clone of 12.5 and restarted. When it reached the desktop it was in Ventura, strange. My 12.5 disk was not available - didn't show in "startup disk" or in "disk utility" so I chose my 12.4 disk and booted into that. The 12.5 disk showed in the 12.4 disk and I restarted again on that clone and I'm back in business.
And Apple, that is why being able to clone discs, I use CCC, is good for users.
