title: Mojave 10.14.3 required for app submission
body: <p>I have a Mac Pro 2010 with the 2.4 GHz Q. Core Xeon E5620 and i am now unable to submit any applications to the app store. I must have at least Xcode 11 to submit an app <a href="https://developer.apple.com/app-store/submissions/" rel="nofollow noreferrer">as per this link</a>. Xcode 11 requires Mojave 10.14.3+ but the machine i have says i cant update the OS to Mojave.</p>
  
  <p>Is there anything i can do at all, other than purchasing another system? Or have Apple screwed me over?</p>
  
  <p>Anyone else managed to get around this issue without having to buy a new machine?</p>
