how can i get my mac to recognize my sony ericsson s500i, i just purchased it last week, all my previous sony ericssons have worked, i plug it in the phone recognizes its been connected to the comp and i select file transfer on the phone, after this nothing happens on the computer no phone icon comes up, works fine on my pc, but i hate pc's and i dont use it, so if anyone could help, do i need a driver of some sort??
