Re: Devices rapidly disconnect/reconnect - Macbook Air Mid 2013in response to staceyaytch

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 helped me and fixed the issue immediately!! Thanks so much for the helpful tip.

Thanks.

Worked immediately.

I'm still wondering what the problem might be... Maybe it's the USB Hotspot...

Wooow - this solution really works (iMac14,1).

Probably there is an issue with device trust which may cause the problem.

Amazing! This worked for me!
Thanks man!

nopes- Didn't work for me.

My iPad Air is still connecting/disconnecting from my iMac.

But there's something else. When my iPad is in this loop trying to connect and then I connect my iphone 6 to the mac, the iPad connects!!!

Awesome, this works for me!

This problem had progressed to where I could not charge any device from either USB port on my MacBook Air (cable didn't matter, devices would charge fine from a wall charger).

I just ran Disk Utility - Repair Disk Permissions and both ports now work perfectly, no more charging issues. No idea why, but I am very, very relieved.

THANK YOU.

This WORKS! thanks so much

I use OS X. What did it for me was to trash the iTunes directory and start from scratch. When booting iTunes I held down the option key and choose to start a new library. Works great now.

Reset Location & Privacy and Disk Utility > Repair Disk Permissions did not helped me. The original USB cable solved the problem.

The solutions presented here are only temporary fixes. They've stopped working for me all together.

APPLE FIX THIS PROBLEM!!! I'm an iPad developer and I can't develop on my MacBook Air because of this!

Any solutions yet any one ? above solutions do not work for me only problems with iPad air to be honest tried repair disk permissions reset settings in iPad restored iPad through iTunes same problem immediately . Keep disconnecting/ reconnecting rapidly !

Also have the same problem with my iMac 5K

I had a macbook and iMac 2010 and this problem didn't occur.

Now i have a 5K iMac since 1,5 month and it connects/disconnects with ALL my iPads ( iPad mini, iPad 3 + iPad air)

But my iphone 5 and 6 are connecting FINE

My devices work fine with my old macbook and old iMac, but when i plug them in my new iMac 5K it keeps bleeping like a maniac and connecting/disconnecting and i get a warning that i should reset all my permissions. I did what anyone else said above these reactions but it didn't work. Also it's not the cable because all my devices work on my older macbook/iMac. Also the iPad 3 and mini/air have different cables ( lightning vs 30 pin)

I think it is the USB port on the computer that doesn't work properly ( i tried ALL USB ports in my new imac without a succes) And it only occurs with my iPads who need more power then my 2 iphones. I think it's the computer

HI,

I have the same problem. Brand new Macbook Air (august 2015) and iPad Air. Have tried several cables and all the fixes here. none work. 😟 Strange thing is that the same cable works on an old iPhone 5. please help!

Regards,

Markus

This is really frustrating!! Plugged in for the first time after Mavericks update, to get a back up of my iPad Air and the crazy stuff happened.

I tried everything mentioned here - from changing cables, repairing disk permission to resetting privacy, network etc. etc.....

But what worked for me was to use a USB hub in between my iPad and my Macbook Pro - suddenly it worked like magic and from a wild horse hopping around crazily, connecting and disconnecting, my iPad went back to its old tame self and meekly surrendered to iTunes :-)

Hope it works for others as well....and Apple does something about it.
