iPhone keeps disconnecting from Mac

ha! this solution worked for me too! but how weird is it??!! there must be an issue with the USB port or cable... but you say it only happens with your iPad and not your other devices. sounds like something apple needs to address...

I had the same problem on my iMac, and I tried everything to fix it, but nothing worked. My iPhone would sync fine in iTunes, but my iPad air would rapidly connect and disconnect. After I had tried everything suggested on this page and nothing worked, eventually, I tried holding the USB cable in different positions to see if that would help. To my surprise, it fixed the problem. Even though the same cord would sync my iPhone and my wife's with no problems, it wouldn't sync my iPad unless I moved the cord slightly in the USB port. To this day, I still have to do the same thing when I sync my iPad air. I don't know why or how it works; all I know is that it does. I know what you're thinking - this is nonsense. There are 4 USB ports on my iMac. It doesn't matter which one I use, this little trick makes it work. I know what your thinking - it must be the cable. I have plenty of Apple cables and I've tried them all, in every USB port; but the only thing that stops iTunes from freaking out when I connect my iPad is moving the cable slightly upwards in the USB port.

i have same issue but i find the way to fix it. Try this:

tap Settings > General > Reset > Reset Location & Privacy. This will also reset your location and privacy settings. You can also untrust all computers by tapping Settings > General > Reset > Reset Network Settings on the ipad/iphone

hope you fix it!!

This actually worked! In my case, I have a 5K Retina iMac and there would be a problem using any cable (including an old 30 pin plus an adapter) and an iPad Air 2. No problems with iPhone. I nudged the USB cable a little in the iMac and boom, no more crazy disconnect/connect problem.

I also have this problem with my rMBP 2013 and my iPad. I tested 3 different cables and all of them didn't work.

I fixed it by using an USB 2.0 Hub (Bus Powered) between the MacBook and the iPad.

The only problem is, that you can't charge your iPad with an USB Hub but you can sync.

This is really annoying. I talked with Apple Support and they said I should replace the MacBook's logic board.

Do you think this could completely solve this issue?

Edit: I found something interesting:

If i launch a VM (Fusion) and connect the iPad directly to the VM, it stays connected. If I then disconnect it from the VM and connect it to OS X (without unplug),

the iPad also stays connected. But if i unplug the cable and reconnect it, the same problem occurs again.

Try this: It may not work, but it worked for me and someone else. I bought a replacement charger wire for my iPhone 5s, and after trying to use it to connect to my Macbook (late 2013), it rapidly connected/disconnected.

Check the "Show Percentage" on your laptop's battery icon at the top right hand corner and then uncheck it. Hopefully this resolved the issue.

Are you using the same cable with both devices? If possible, use another cable. Also, disconnect all other USB devices while syncing.

Otherwise, follow the applicable instructions on the page linked below.
