Stuck on Options screen
A power shortage happened while installing Monterey on my M1 iMac (2021)
Now I’m stuck on the Options screen after restarting.
Command-D on keyboard won’t work.
Holding Power button while restarting won’t work. Leave it be overnight won’t work. Unplugging everything for an hour then restarting it will only show the Options screen with carousel turning. Keyboard or mouse won’t connect.
iMac 24″, macOS 12.0
