Q: Repeated "AirTrafficHost" errors in console after 11.4 update; CPU spikes

I am having a very similar problem on my old iMac CD running 10.6.8  After updating to iTunes 10.4 it repeatedly gives ATH Quit Unexpectedly ignore/send to apple dialogues. It looks very much like a bug when syncing to iDevices over wifi. Not the first chronic iTunes bug linked to 32 bit OSX But probably the most irritating to date. ITunes now completely unusable for me. Apple shambles again. ITS A BUG APPLE, FIX IT!

Same problem here, same OS version, same hardware (except is 2GHz, 1GB of ram and white)

I think maybe a crash log might help

Bye!

Yes got exactly the same crash logs. I re-installed iTunes 11.3 but the problem persists. Presumably the buggy framework was not reverted. As I don't run Time Machine on this machine I'm going to have to try reinstalling from the 10.6 disc - if I can find it :-) I'll post the outcome on here.

Thanks, working perfectly for me now in conjunction with iTunes11.3.1 which I downloaded from softonic.com. You saved me a lot of hassle, much appreciated!

I did like you said and now it looks like it's working fine.

I guess when Apple will update iTunes we should do that procedure again if they don't solve it (and I fear they won't: Intel 32-bit hardware is obsolete for Apple as far as I know)

Hey all,

I am having this problem on my old CoreSoloMini (23bit) since updating iTunes last week. Only I am getting an error alert saying "ath quit unexpectedly" when I connect my iPhone 3GS and launch iTunes 11.4. The alert will go away for a few seconds when I hit "Okay", but returns after a couple of seconds. Total drag.

I grabbed the zip file, but I don't know how to change a system framework. Of course the Finder does not like me dragging the old framework out of the PrivateFrameworks directory. I assume I use the Terminal, but what is the process? I have tried searching for how to do this, but am nervous that I will screw things up worse if I do it wrong.

Provided that you are logged in as a user with Admin privileges you should be able to just drag and drop using the Finder. You will be asked to enter your user & password & then it will do the copies. You could use the terminal to do the delete and copies but you will still be asked for a your password.

Well, that was easy all right. Thanks a bzillion.

I managed this (had to delete MobileDevice.framework before copying in your version, but was able to replace the other two).  Now I can back up my iPhone 5c with iOS 8 to my Macbook 10.6.8 with iTunes 11.4.   (and have done so now).

I wish I had found this out last night:  I downloaded iOS 8 through iTunes  (took over two hours) and then I couldn't upgrade my iPhone.  SO, I upgraded the iPhone directly (another 2-3 hours).

Anyway, thank you SO much.

I'm not having that problems, but, as you say, it works with USB which is what I'm using.
