I'm obviously not explaining this properly. Almost everything else: drives, phones, cameras, SD cards in card readers, CF cards in readers, satnavs, thumb drives, other computers, CDs, DVDs mount on the Mac desktop as effectively an external drive which is a lot more convenient for various reasons. This phone doesn't. Even the MicroSD card taken out and put in a card reader doesn't.
Yes I know you can do it with Android File Transfer. First remove Kies altogether.
