Hello.
I'm trying to restore my Early 2011 Mac Pro OS X 10.7.5 to the latest OS. I've read https://www.imore.com/restoring-high-sierra-older-mac-tougher-you-think and realise I need to upgrade to OSX 10.8 first.
I had done an internet recovery to reinstall the OS which was 10.7.5. However, I dont see any of the older os x in my App Store Purchases. Now every time I try to use App Store for downloading El Capitan or Mojave, the app store keeps throwing 'we could not complete your purchase: unknown error". I've tried resetting passwords of AppStore & Itunes, cleared cache & cookies, restarting etc. Nothing works.
Could someone please guide how I can upgrade from 10.7.5 to 10.8 (without having any of the older os x under my App Store Purchase) so I can finally upgrade to the latest OS? Many Thanks
