My Macbook doesn't import or copy photos from Galaxy S3 There are 663 photos in my camera. I want to share some of them them via computer with my mother who does not have a smartphone. 


My phone and computer are connected via USB cable. 
The Android File Transfer app is installed and working up to the point of showing me a window on my computer with choices of files to transfer. 


However, when I click on DCIM or Pictures nothing comes up. Similarly, nothing happens when I click on Camera. 

What am I doing wrong?  How do I get those photos from my phone to show up in my computer? And will they be in both places?  I'd like to keep them in my phone also. 

Thank you.
Connect the mobile in Mass Storage (MSC) mode instead of MTP mode. You'll find this setting in Connectivity section. MSC mode will mount the memory card to the PC just like USB storage. You can now copy contents more easily (or)
Use the Samsung's KIES software for handling all the media.
