Why does my iPad keeps connecting and disconnecting from the new late 2013 iMac

Played with this one in Yosemite as well now, and have solved my issue. After changing USB ports numerous times and even trying a powered USB 3.0 hub as well, it looks like it was the cable. While 2 of my cables (that are older) don't seem to work well with it anymore, I borrowed my sons newer cable and that seems to work fine. It must be something due to the age and deterioration of the cable after prolonged use/charging. Try to borrow another cable and see if that works, as it did for me.

Charge ur ipad to full battery 100% and connect it to your mac. It's just that ipad tend to disconnect from low power connection. This should solve the problem.

Make sure the iTunes on your computer is iTunes 11.1 or higher.

Have you authorized this computer on iTunes?

Since your iPad was probably synced with another computer it will resist being synced with a new one unless it "knows it's yours", so to speak....

Same problem. I can tell you it has nothing to do with the iTunes version you're running. It's more indicative of a hardware/firmware problem of some sort.

I have the same problem. Connects and disconnects. Does not always do it. MacBook Air Mid 2013, and iPad Mini retina. Plugs into wall fine... Any solutions yet?

All seems a bit drastic! 😕

Well, I did nothing and the problem disappeared. Then now suddenly it's back, making me go back to this thread to check if there's any solutions yet.

😐

Same for me - iPad 2 & iMac 2013. It happens sometimes. I created a bug report with number 17022827.

Thanks for suggestion, I will try.

I have the same problem. I changed of USB port, now it seems it is working (it's syncing right now). Hope that works, any way is frustrating this random problem.

I have had the same issue for about 2 months now with 3 3rd Generation iPads and a current model iMac 2.9 GHz. it was under warranty so the Apple service provider put in a new motherboard and bluetooth chip. That didn't make any difference, so Apple replaced the entire unit having verified hardware failure. the first day with the brand new iMac and the issue persists.

P.S. It also thinks my iPhone needs to be set up every time I connect it with the USB cable to my Macbook Pro.

This did not work for me, it went through the cycle of connecting and disconnecting for about a minute or two then switched to “Not Charging” and ended up not syncing.

This time around though it’s charging and syncing on its own. But I still don’t understand why it just works sometimes and doesn’t work the other times.

edit: After reopening iTunes. Thanks
