Where to download older OS version from App Store?
How does one download an OS from the App Store for the purpose of creating an installer drive? I recently got a 2018 Mac Mini that came installed with Monterrey, and I have lost too much functionality with this OS so I need to revert to something older ASAP. I downloaded Mojave from the App store, but when the download completed it gives me an error "This copy of the “Install macOS” application is too old to be opened on this version of macOS." I cannot locate where the App Store downloaded the OS to on my hard disk.
Thanks for any guidance.
Mac mini, macOS 12.1
