Don't have password to access my Mac Pro the new update requires password
I don't use a password to access my Mac Pro. The new Tahoe update requires a password to restart, update now and update tonight.
The password needed to make such changes is the login password after an Admin user.
if you do not have an Admin user with a password, create a new Admin user for just this purpose.
The 'Approved Method' for using your Mac without a password is to actually have a password, but to change macOS settings so that password is not required to log in (auto-login).
