Wait, let me understand this...
If I upgrade my iPhone 6 to iOS 9 using the OTA update and it fails, then I am supposed to plug it into my Mac Pro 1,1 and restore the iPhone using iTunes 11.4 with my last backup.
No wait, my iTunes 11.4 doesn't recognize iOS 9 nor my iPhone 6 anymore but says that I need to purchase a new computer running 10.8 or higher in order to restore my iPhone to correct the problem that Apple created.
Hummm, I wonder if I can force Apple to give me a new computer because of their mistake?
Would be nice to run that one on them... but they will just tell you to: a. get bent. b. take it to the Apple Store.
