Q: iTunes 11.1.4 freezes after connecting iDevices

Hi all,

I have the same problem as others (with error messages including "Syncing cannot be enabled on this computer"). I tried the easy fix above, but when I look through ~/Library/Application Support there is no folder for SyncServices or iSync. I tried searching the hd for both of those, and the only thing that came up was SyncServicesAgent, with a microsoft outlook icon.

Any ideas where to find syncservices or isync, or what they were replaced with? I'm running a late 2012 macbook pro, OSX 10.9.4, iTunes 12.0.1.26, iphone 4s with ios 7 and ipad air ios 7.

Many thanks,

Rick

Thanks enormously!!!!!! Works for me... very grateful

What's the Windows equivalent of this procedure? Thanks!

Thanks for this directions OtterStCatch!

This worked for me. I have a Mac. To get to the library folder you need to click finder, then GO, then hold down the option key and the library folder will show up.

Updating from 11.3 to 11.4 worked for me.

I'm afraid I don't know the Windows equivalent.  Anybody have ideas?

OMG This actually workkksss!!!

Worked for me with Yosemite and Itunes 12. I've had this issues for over a MONTH.

Yay!! Why the **** could apple not come out with such an easy solution?

THANK YOU ALL SO MUCH!!

Thanks work perfect for me, i have search for a solution in months, today i find and follow your instruction

Thanks OtterStCatch and luckyj671.

I've searched for this solution for months!!! When I found OtterStCatch's solution I still could not fix my iTunes since I couldn't find the Library folder. Luckyj671 showed how to find the Library folder and OtterStCatch's solution fixed it for me.

Thanks guys!!

I've spent hours trying to fix this problem, restores from time machine, new libraries you name it. Finally found OtterStCatch's solution - like others, worked for me.  For anyone else searching, this solution fixes "itunes becomes unresponsive immediately when any device is connected". - the dreaded spinning beachball. Great find OtterStCatch. 

Does anyone have a solution for Windows? This is really frustrating!

I *think* the equivalent path at least for Windows 7 64 bit is: C:\Users\<you>\AppData\Roaming\Apple Computer

Unfortunately for me after removing SyncServices and starting iTunes (12.0.1.26) attempts to Sync still cause iTunes to crash.

Thanks worked a treat IOS8 Yosemite. Very frustrating after trying a full restore on my phone.

Fwiw after a rebuild of my iTunes Library (Windows 7), I'm now able to Sync my iPhone 6 without crashing. I never did have to reset my phone, though I did try most if not all of the suggestions prior to the rebuild so perhaps it wasn't the rebuild alone which helped in my case. I know this thread is more Mac focused but I thought I'd share this anyway as it appears other Windows users are looking for answers.

As another data point, syncing my phone in iTunes 12.0.1.26 to my Macbook Pro (OS X 10.9.5) to a new library (had never synced to it before) did not have any problems at all.

How do you rebuild your iTunes library using Windows without losing your music?
