Why is my Macbook murdering iPhones? Help!

[mandobud16]

Hello!

I have an issue with my phone 6 where it is not recognized by any computer when connected via usb. I haven't been able to connect to iTunes for over 3 years. I recently acquired another iphone 6, plugged it into my macbook pro (2015, High Sierra 10.13.6), and all seemed well. I was notified that the phone needed an update so I proceeded with the update. During the update, I received an error that the update could not be completed. Now, iTunes doesn't recognize the newly acquired phone either. Additionally the phone is stuck with the screen telling me to connect to iTunes, which I cannot. I tried to connect to another Macbook Pro, with no luck. I see no iphone under the USB Device tree on either computer.

I find it interesting that I now have 2 iphone 6s, neither of which will connect to any computer. I tried updating iTunes, Hard reset, DFU mode, PRAM reset, different cables. No luck.

Does anyone have an idea as to what might be happening? Why is my Macbook murdering my iPhones? I have since backed up my old phone to iCloud and really want to be able to use my newer phone. Any help would be much appreciated!

When you say you updated iTunes - to which version? The latest? Or just the latest that will run on your current OS?

Are you running a high enough version of Mac OS to be able to update to the latest version of iTunes?

I'm asking because I've been in the spot where I tried to update an iPhone 4s on a Mac running Snow Leopard. iTunes was fully updated for Snow Leopard, but even though iOS 9 was old at the time, because I was using Snow Leopard the update errored. I had to use a PC that was capable of running the latest iTunes in order to make the update work.

Apple has the wonderful ability to cut things off if you aren't upgraded far enough.
