I have a Samsung galaxy s4 and a Macbook pro. I tried last night to transfer my photos from my phone to my computer.
First the Mac doesn't recognize the s4.
I downloaded Android file transfer and it doesn't recognize my phone either. I've switched back and forth between mtp and ptp and even turn USB debugging off and on.

I can't get my pictures off my phone!!!

I have Dropbox but already maxed out my memory.

How can I get my pictures off my S4?

(I want my iPhone back)
