Unable to download app on my MacBook Air running macOS Big Sur from App Store.
I'm completely new to Mac. I just bought a used early 2014 Mac Book Air. I've upgraded as far as I can to Big Sur. It won't let me download app from the App Store. I guess it's too old to update further? Is there any way possible to fix it to download apps at all. I can't afford a newer version at the present time so thats out. Is there any other way?
Thanks in advance,
Amanda
