I have just installed the xcode before I resync with iTunes.
I got this problem after sync with iTunes.
My mac running 10.8.2 and latest iTunes 10.7 (21) 64bit. I tried some advices from web but I have no luck:
1. Use sudo to remove the iTunes and resinstall it but it didn't fix the problem.
2. Use Timemachine to restore the AppleMobilexxx.kext and it also didn't fix the problem.
3. I tried to delete all backup ~/Library/Application Support/MobileSync/Backup/, no luck too.
4. I tried to reset the syncservices folder too http://support.apple.com/kb/TS1627
What else can I do now?
