I cannot install GarageBand
I have a Mac running Catalina 10.15.7. Up until recently, I am sure that GarageBand was installed on my Mac. I never used it because I never had the right hardware, but I have just received come hardware for Christmas and when I went to open Garageband, I found it had disappeared.
When I go to the App Store and try to reinstall GarageBand, it says "GarageBand can’t be installed on “Macintosh SSD” because macOS version 11 or later is required."
So I tried to install macOS version 11 (i.e. Big Sur), and it says "The requested version of macOS is not available."
So I'm stuck!
Can I install an older version of GarageBand?
