I just got an iPhone 6, upgrading from the 5.
My main computer is a Mac Pro Running Snow Leo, and iTunes 11.4. I backed up the iPhone 5 and when I went to sync to the 6, I got a warning that it wants a higher level of iTunes. I went to the other Pro running Yosemite and iTunes 12 is there, so I backed up the 5 to that computer. The apps don't show up to add back to 6, nor does the 5 backup show to copy it over.
How do I get the apps to transfer? (If I need to transfer all of iTunes from the Snow Leo Mac to the Yosemite Mac, and just update iTunes in place, that's ok too. I'd just like a hint at the best method to get this new phone up and running)
