My MacBook Pro (11,4) is outfitted with macOS BigSur. A non-admin account provides access to the machine. I'd like to upgrade it to macOS Monterey, however, admin account is needed.
I am okay with backing up (Time Machine) the non-admin account and reformatting the machine from scratch with macOS Monterey.
That being said, if I am making his harder than it needs to be I'd like to know. What is the simplest path to upgrading to macOS Monterey?
