Does drop box work with music and movies for the S3 ? I am trying to make it as easy as I can for my daughter to upload them to her phone.
Sounds like your S3 is set to be a MTP when connected via USB. I have the same setup. When you plug in your phone to the mac on the notification screen it describes the USB connection you have. Click on that and then select to show the phone as a camera.
After that when you open iPhoto your phone will show up.
Good Luck
Are you sure you're using a data cable? If you were using a charge-only cable then you'd only see the charging activity indicator. Are you seeing that?no notification screen shows up referring to the USB connection
