I've read quite a few reports of this problem, some that have been easily rectified, but unfortunately it seems I don't have an easy fix... let me explain: Ok, my Macbook Pro is OLD but after a few little hardware upgrades runs really well. It's a 2006 c2d: http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-2-duo-2.33-15-specs.html and therefore the latest OS I can run on it is Snow Leopard. It's super stable so I'm totally fine with that to be honest. As my OS is so old, the version of iTunes I'm running is old too (11.4). It's the latest version that runs on my mac. Again, it does everything I need it to and synced perfectly well with my iPhone 5S on iOS 9, so all WAS well. Last week I finally updated my iOS to 10 and I was surprised to see this message pop up in iTunes: iTunes could not connect to the iPhone “(iPhone name)” because an invalid response was received from the device. I also used to transfer my photos manually with Image Capture, that now comes up with a notification that my iPhone is locked. I've tried AnyTrans, but it seems my OS is too old... I then found an old version but my iPhone doesn't ever appear. I imagine it's because my phone's iOS is too new. All the solutions I've seen revolve around updating iTunes, which I can't do. I would love to be able to go back to iOS 9 but I don't have a recent back-up of my phone using that iOS. So as you can see, I'm stuck between a rock and a hard place. What can I do? Is there any software out there that will let my ancient mac connect to my phone?
