Early 2013 MacBook Pro Retina 15”
Bought the computer brand new from an Apple Store, had the store partition it and add Windows so I could run my Architecture Programs. Fast forward, tried to Factory Reset the computer myself and let a friend use it. It wouldn’t work for him. I have the computer back and can’t get it working right. About This Mac shows Software is OS X 10.8.5 . Click on Software Update for ITunes 12.4.3 and get 102 error. Try to sign into ITunes but need a Software Update. Someone help
