Question:
i got a new mac, because my old pc died. How do i sync my iphone with the new mac without losing all the songs i already have on it? Please help me.
Answer:
Authorize your new itunes on your new Mac.
OR put all your songs and other datas in your USB or Hard-drive and simply plug them in your new Mac. It shouldn’t have a problem with songs and videos but with applications you have to authorise it in able for those application to be installed in your new Mac itunes. ;]
Or you can try the icloud as well
