iphone keeps reconnecting to macbook
Hi there,
I've got a iPhone 5s and a 2013 Macbook air (yosemite, 128gb) and whenever I plug in the usb cable to connect the two it often (but not always) spends a few minutes seemingly connecting then disconnecting before working consistently. The funny thing is this exact same problem happened with my iPhone 4s, so I can rule out the cable (of which i've tried many to be sure) and the phone - mentioned it to my housemate who also has a 2013 Macbook air and he has the exact same problem so I can rule out the macbook as well.
You'd be helping us both out with an utterly infuriating problem if you can shed any light and be assured of my eternal (if not just long-term) gratitude.
A thousand thank-you's,
Tim
