I just installed Monterey onto an external drive from a boot installer. Everything seemed to go correctly, except when it the installed finished it never went into the OS. I can select and assign the volume as the startup disk in System Settings/General, but when I try to Restart I get this
What does this mean and why is this happening?
I'm on an M1 MBP currently in Ventura.

Not really sure this is applicable to your situation
Maybe worth a look see ?
Thanks for the link. Oakley is always an interesting read.
Shall observe and hope all goes better with this issue before the Total Eclipse on Monday
Then, we may all be in the dark for maybe 2.5 minutes ( depending on location )
