Big Sur -- what to do if an upgrade to Monterey says "You must provide authorization..."
If a “Standard” account user on an M1 (or greater processor) mac tries to upgrade the operating system, they may see a message like this:
(This is currently an issue upgrading from Big Sur 11.6.x to Monterey 12.x)
There are three recommended ways to upgrade the operating system at this point:
Log out of the “Standard” user account and run the OS Upgrader from the “UM-Support” account.
Use a Monterey boot stick to upgrade the OS.
Make the “Standard” user an “Admin” user by following this link and then the user can run the upgrader themselves.
