iPhone keeps disconnecting from Mac

That did the trick for me! Fixing disk permissions with Disk Utility. Thanks!

Resetting SMC helped me to overcome this. Resetting the System Management Controller (SMC) on your Mac - Apple Support

Thank you all so much for your many helpful responses!

I placed a USB 2.0 hub in my iMac 5K, but my iMac won't recognize any device 😟 It's a trust USB 2.0 hub with 4 ports but non of them work on my iMac

The problem still exist, i tried it al.. the SMC reset, reset permissions, disc permissions, delete the ipads and begin from scratch, but non outcome.

My system logs show this after the connect/disconnect happens:

Tried to connect the iPad again and again the problem occurred. Got this in my system log:

Hi,

I have the same problem with 2014 Macbook pro + iPad Air 2.

The laptop works fine with older iPad 1

The Air 2 works fine with older 2012 Mb pro

The problem is intermittent so sometimes iPad connects. In the beginning it connected in 1 of 2 attempts now it does in 1 of 20 so the problem seems to be worsening with time. What is also bad is that after iPad is connected, laptop's keyboard and trackpad stop responding until I insert something else in another USB socket. Laptop's system log contain all these usbmuxd AMDNotificationFacepalm messages that are completely useless. I think it is a hardware/firmware bug in laptop's USB controller, somehow related to USB charge current.

I do not really need to charge the iPad from USB but at least I need it to connect because I am iOS developer. This bug is really frustrating especially because there is no easy way to repair/replace Apple stuff in my country.

The following suggestions did not help:

1. Resetting the iPad

2. Restarting the laptop

3. Resetting SMC

4. Resetting Locations and Privacy settings on iPad

5. Using different USB cables, "original' and non-"original"

6. Quitting iTunes and iTunes helper

7. Deleting files from /var/db/lockdown

8. Quitting VMWare Fusion

9. Moving USB cable in a socket or inserting it slowly (it helped once)

Here is what helped:

10. Use USB hub.

iPad does not charge from the hub but at least it can sync and exchange data.

I hope this info will help somebody.

Best regards,

Bob

thank you for your input, i can relate and tried exactly the same steps, but nothing works

***** big time.. i thought maybe OSX el capitan will be the answer to all of this, but just updated and the problem still exists.. now i think it looks more like an hardware default then a software default 😟

Someone on this thread had the right idea. The problem appears to be with iPad drawing too much current for the mac to handle, so one of them disconnects. (I think the Mac kills the power).

Also, the iPad must be drawing a variable amperage depending on how much battery is left. A battery with 10% on it will draw more current than 80%. And that seems to be what triggers the mac to kill power, disconnects the ipad, which tries to reconnect and goes into an infinite loop. That would explain why switching a cable seems to work "sometimes" - it's a red herring.

I charged my iPad air II on MBP 2015 from 8% to 75%. Without issue. Then I could charge it from 75% to 100% on the iMac 2014. Where as a discharged iPad would go into an infinite connect/disconnect cycle.

It's very unfortunate that the USB ports on the back of iMac are not designed to generate the right amount of current.

I had this problem and it was very odd in the way it suddenly appeared. After much googling with no definitive answers I ended up fixing it by slightly pressing (and bending) the hollow side of the USB plug to make sure it grips onto the connectors properly. This has completely fixed it for me. I would suggest anyone with this problem should investigate cabling, especially how well the USB plug sits inside the USB port of the computer.

HOLY CRAP!

This is crazy, but this stupid problem was plaguing my iPhone 6 and iMac, and I couldn't find the answer.

Was working for hours. Tried everything.

Then, I closed out of all my apps opened on my phone (***) and it worked again! must have something to do with the power draw

I had this issue on my macbook air and iphone and ipad

The fix for me was to disable personal hotspot on my ios device. after that they both connected fine via usb

hope this helps

Will Apple someday fix this???

I've noticed it happens since some years ago lol, and it's very frustrating...

I've a rMBP 2014 with El Capitan and an iPhone 6 with iOS 9.0.2. and the problem persist yet... I've a cheap hub and plugged it in the faulty USB port (the left one, the right one works good) noticed that the charge rate is lower but it worked fine, it opens Photos app and the problem is gone, then I removed the hub and it was working mostly well (Photos app doesn't detect it, but iTunes does, the low charging persist yet, it charges way better in the right port).

Is funny to see that other guys with the same problem that went to a Genius Bar cause they though it was a hardware failure (when obviously is not, cause the port works **** well with other devices like mouses, bluetooth dongles and even an iPhone 5s lol) got a brand new MacBook Pro cause they couldn't fix it, I mean... did they even tried it???

APPLE FIX THIS **** PROBLEM, IT HAS YEARS HAPPENING!

Thank you man. This helped me.. Don't know how and why.. But it helped..

It's 2016, upgraded the MBA to El Capitan, and it's still happening, so matter how many of these "tips" I try. Sometimes switching USB ports or cables works, but most of the time it does not.

Really getting frustrated, Apple.

It's no wonder companies like mine are abandoning the iPad/iPhone for their enterprise mobile device strategies, and the iPad Pro is failing to catch on for business.

Hi Folks,

I have the same issue on my MacBook Air (13-inch, Early 2014) x Iphone 6 charging.

I've just found in another post someone suggesting to use and USB 2.0 hub, for me that actually worked!

Is no a solution but a workaround.
