My iMac recognises my iPhone as new
Hello everyone,
Whenever I plug my iPhone 6 into my iMac and go to iTunes to import some songs to it and sync, it says, 'Welcome to your New iPhone'. I have had my iPhone for the best part of 5 months and it has never done this before. However, I spoke yesterday to an Apple customer services person on how to make my iMac faster, and he told me to delete some cache files. I was thinking that could be the problem?
Anyway, on Photos (which opens instantly) it says 'ready to import'. So it's as if just iTunes' details have been removed. I was considering selecting 'Set up as New iPhone', but I was worried it would remove all of my applications, photos and the like. Please help as I cannot currently use my iPhone with iTunes, which is needed for me right now!
Thanks to everyone who attempted to help me!
