This version of macOS 10.12 cannot be installed on this computer.
What does this mean? I try to download from the App store and I get a popup saying "This version of macOS 10.12 cannot be installed on this computer." I click on "Learn More" and nothing happens. I just recently upgraded to El Capitan without issue. I'm currently running a mid 2007 24" iMac that works as good as the day I bought it! Help!
iMac, OS X El Capitan (10.11.6)
