iTunes won't sync after Lion 10.7 install

I've looked around and it appears that this issue has been coming up in a few different iterations, I've tried some of the Apple Help hardwiring and nothing is working yet.


It's this simple. My iPhone and iPods synced up fine with Snow Leopard las week but do not open iTunes or appear when iTunes 10.4 are opened.


I've tried reinstalling iTunes and the old procedures under http://support.apple.com/kb/TS3540


Nothing working yet.

iMac, Mac OS X (10.6.8), Model 7,1 2GHz / 2G

interesting, i have a sync problem with an unmentionable app on one unmentionable-state of iPhone...won't sync wirelessly anymore, but with wired, all is well here. But r u syncing podcasts by any chance...as i have seen where a corrupt podcast, or an error during syncing one causes a -50 error. Just deselecting / syncing / reselecting fixes that. Cheers!

I was a bit lazy last night and overlooked what may have been a relevant tidbit:


In applying the procedures of the Apple recommended fix — http://support.apple.com/kb/TS3540I did not find the file "com.apple.usbmuxd.plist~orig," this might be part of the problem and may help in debugging. I just went on with the rest of the procedures hoping for the best.


Once again, it should be pointed out that the Support fix was from a couple weeks ago and most definitely pre-Lion.


My apologies for the oversight…

Here's a small update to the issue:


After an espresso I pulled out my MacBook Pro [ Intel T9800 2.93GHz / 8G Model 5,2 ], hooked that up to the network and attached the iPhone.


It started to work properly, meaning that it started up iTunes (and Nikon Transfer) and mounted under "Devices" in the iTunes window for about 30 seconds. Then it disappeared!


In trying to sniff out unresolved issues I went looking for that launch Daemon "com.apple.usbmuxd.plist~orig" …


Whadyaknow? It sill isn't there!


After a few minutes I tried unplugging the iPhone, quitting iTunes and reattaching iPhone to USB cable. Now it does not work as my older iMac. Nikon Transfer doesn't automatically start up as well. The iPhone does not show up in "Devices" when I start up iTunes manually…


Looks like I won't be able to upload the latest King Unique (#20) mix to my iPod for cruising…

I have it solved on my MacBook Pro now. In the support procedure I did the following


f the issue remains, try these steps:

  1. Disconnect the device and quit iTunes.
  2. In the Finder, locate iTunes in the Applications folder and drag it to the Trash. (This will not remove any of your iTunes media or your iTunes library.)
  3. Choose Go > Go to Folder. Enter the following location into the text field that appears:
    /System/Library/Extensions
  4. Click Go.
  5. Locate the file "AppleMobileDevice.kext" and drag it to the Trash.

After this I rebooted the Mac and now reinstalled iTunes (without deleting anything of iTunes)


After installation I started iTunes and connected my iPod and it was recognized, now I connected my iPhone as well and was also recognized.


When it was not working I als found the following error in my system log


0 0 AppleUSBCDC: start - initDevice failed


Hope this helps everyone in this thread as well!

Peter,


Let me be clear. When you say "I just deleted that one file…" it's a bit grey as to what you're referring to. When I try your first two steps…


  1. Disconnect the device and quit iTunes.
  2. In the Finder, locate iTunes in the Applications folder and drag it to the Trash. (This will not remove any of your iTunes media or your iTunes library.)


… I cannot drag iTunes to the trash without getting "iTunes can’t be modified or deleted because it’s required by Mac OS X"


-------------


Now, I cant find any reference to "AppleUSBCDC"


But I did get:


IOSurface: buffer allocation size is zero

IOSurface: buffer allocation size is zero

Kext com.apple.driver.AppleMobileDevice not found for unload request.

Kext com.apple.driver.AppleUSBEthernetHost not found for unload request.

Both of those seem fairly ominous…

Warning OFF TOPIC


PS: If it isn't one thing it's another…


In using Terminal I found another little "bug." I have a startup command for Terminal (repeat, this is about Terminal, not iTunes) …


User uploaded file


… so that I can shorten the prompt to ""#" instead of all of that other relevant nonsense. That startup command is not working for Terminal. I know this is off topic, per se, but I'm just seying…

Thanks a lot, Peter, totally worked for me. For those who can't delete tTunes, I got the same error message by trying to delete iTunes from the finder window, but it worked fine with AppCleaner. Search for iTunes, deselct everything but iTunes and delete it. The .kext file could easily be deleted anyways. Reinstalled iTunes and there we go, syncing all smoothly again.
