I just upgraded from a GSI to a GSIII. With my old handset, I could transfer files between phone and computer (iMac) just by plugging the phone into my computer. I had the phone set as a storage device in settings. Now with the new handset, after plugging it into the computer, nothing happens. The phone does not show up on my desktop at all. The handset is set to Media device (MTP); there is a check mark next to this option. But still my iMac does not recognize the phone. I tried using Kies but I have NEVER had any luck with Kies. That is one CRAP piece of software! Any suggestions anyone?
