Hi I just got my iphone 6s today, updated it to ios 10. Anyways I keep getting this message when I try to connect it to itunes "iTunes could not connect to the iPhone ?iPhone? because an invalid response was received from the device." I already tried restarting the phone... any luck? I heard you may need the new OS on the macbook for it to work... I hope not!!! I have an old 2011 macbook
