I need to reinstall Numbers
I was advised by an Apple support person over the phone to erase my hard drive and reinstall macOS on my machine (iMac Late 2012). Upon reinstalling Catalina 10.15.7, I attempted to reinstall Numbers. However the App Store says Numbers is not compatible with macOS older than 11.0. When I went to download Big Sur, the Software Update screen opens reading, "The requested version of MacOS is not available."
How do I get Numbers back onto my machine?
