Having the same problem with error 9912 trying to transfer photos from iPhone 5 to MacBook. Another 20 minutes searching for solutiong and NOTHING> For all of Apple hype, advertising and high cost of products I rate the iPhone 5 Terrible and give a rating of 1 out of 10. User should be able to connect iPhone to Apple computer and have it function as an external drive with EASE of transfer of pics, files, etc. TERRIBLE disconnect and lack of function, Apple products VERY difficult to use. Don't know if Google products are any better, but switching to find out.
Problems with iPhone:
visual voicemail freezes after deleting one voicemail
iPhone will NOT work with aftermarket charging cords
Can not transfer pics from iPhone to Apple / Mac computer easily
Can NOT transfer files from iPhone and Apple / Mac computer easily
iPhone battery draining and often dead
Apps dissappear randomly and must be re-purchased or downloaded again
DO NOT buy an iPhone.... they don't work
