    I've got a mid-2007 iMac that does not appear to be able to run 64-bit kernel and has 10.6.8 Snow Leopard. I've installed iTunes 11.1 beta 48 and have the .ipsw file all ready to go. However....because I'm on an older iMac, I get the error "iTunes was unable to load data class information from Sync Services" whenever I plug in my iPhone 5 to install GM. I'm thinking that installing GM will work but I won't be able to sync it until the official 11.1 comes out next week and the final bugs are fixed. But I'm honestly nervous about causing more problems than it's worth at this point. What are my options and do you forsee major complications??

    Mid-2007 iMacs are the oldest to support Mavericks/Mountain Lion. Yet they do have a 64-bit kernel and are able to handle iTunes 11.1 and iOS 7 GM. Not sure what your problem is.

    I ran a Terminal command I'd found last night to turn on 64-bit kernel functionality on my iMac, but it didn't take. How exactly can I go about switching that on?
