Base build is not compatible for this install method - macos upgrade
I'm getting an error trying to upgrade my macOS on my M1 Mac Mini to 13.4.1. First time i've had this problem.
'The base build is not compatible for this install method. An error occurred while downloading the selected updates. Please check your internet connection and try again.'
I've tried installing on my standard user and admin user accounts. I've tried creating a new admin account to install it, still no resolution.
Mac mini, macOS 13.4
