A friend of mine has an Intel iMac "Late 2006" with OS X 10.6.8 and iTunes 10.7 and an iPhone 5 with iOS 6.01. According to Apple's iPhone specs it should be possible to sync from this Mac to this iPhone via iTunes. It does work with apps and music but it does not work with contacts. The contacts are stored on the Mac in the default 10.6.8 "Addressbook" application. The iPad is connected to the iMac with a cable. Automatic syncing has been disabled in iTunes. In iTunes (Devices - iPad - Info) "Sync Contacts" is checked and after clicking onto "Apply" a sync is set in motion but when it has finished no contacts are in "Contacts" on the iPhone. We tried this with and without having in iTunes under Advanced the option "Replace information on this iPhone: Contacts" checked. The result is always the same - no contacts on the iPhone. Does anybody have any idea what is going wrong here and what needs to be done to get the contacts synced? Thanks!
