Restored Mac Mini late 2012 to 10.8.5 and want to update to 10.15.7 Catalina. Cannot connect to app store on this computer for some reason. On my Mac Mini 2023, the app store will not let me download Catalina - says not compatible with this MacOS (Ventura). I wanted to make a bootable flash drive.
To perform this action will require booting from a Bootable Installer.
The Bootable Installer can Only be performed on an Apple Computer
This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer. Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.
Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.
Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
