Speaking of Monterey, does anyone know what is the last 12.x.y version-number for which CCC6.1.1 is able to successfully create a Legacy Bootable clone of the active volume that (important) is actually treated as the original rather than a copy by the OS (i.e., won't have reduced permissions or other restriction, such as full access to system updates)? (This is for non-silicon systems.)Yes, you need to use CCC’s Legacy clone option. I used it to clone my 5,1’s Monterey 12.6 install to a better NVMe SSD, which obviously needed to be bootable. Didn’t have to Bless afterwards.
I've always used OPTN to bring up the bootpicker, since the G4. Is OPTN what you meant? As far as I know, the CTRL key does nothing at boot.Booting with control key doesn't bring up the boot picker as it used to so I'm a bit at a loss.
