Hi, I have finally had my 4th imac delivered which I will be keeping. Having updated to the latest itunes software etc i connected my ipad to my new mac and it started synching all my photos etc The problems i have are that the ipad apps will not synch over to my itunes everytime i try it says that if i synch i will lose all data on my ipad as it will synch from my new itunes library which obviously does not have anything ipad related on it. Now before i received my 4th replacement i had successfully synched my ipad on the original imac which was delivered in November, does it have something to do with this? My itunes account states that i have 3 pcs authorised to us my account whereby it really should only now be 1 the one that i have now. The lady at apple said that all the macs will be reset so this should not be the issue no? Any advice?
