How to install Catalina on Late 2012 Mac Mini - missing from the App store
I have a late 2012 mac mini currently running El Capitan.
The latest supported macos is Catalina, which I would like to upgrade to.
However Catalina does not show in the App store - only Big Sur which is not supported on this machine.
How do I upgrade the device to Catalina?
Many thanks
Mac mini, OS X 10.11
