So I have an iMac(21.5-inch, Mid 2014) , and Im told I cannot upgrade to Catalina, so the tech sent me all the back to Sierra. Now my iTunes won't work unless, it says, I upgrade my Mac. What do I upgrade to?
iMac 21.5″, macOS 10.12
It can run Catalina and then Big Sir when released.

However, if you are using older software then it might be best to run High Sierra or Mojave.
