Connecting a Galaxy S3 to my MacBook Pro 10.10.5 I am trying to connect my Samsung Galaxy S3 phone to my OS X 10.10.5, with no luck.

I have tried all sorts of different cables, and have checked USB debugging. The phone successfully charges when plugged in to my computer. But it doesn't show up in Android File Transfer or adb devices.

What should I do? Do I have to install a driver of some sort? I have read mixed reviews of something called Kies, some saying DONT install it, others saying DO install it.

Update: I tried downloading Kies, and not only can I still not see my device, but Kies says that I cannot use Android File Transfer as long as Kies is installed, and that I need to uninstall Kies. WTF Samsung?
I have faced the exact same problem when I first started android development. My One Plus One would simply not show up in Android File Transfer. I would highly recommend that you re-install Android File Transfer.


Install Android File Transfer app.
Reboot your Macbook Pro after installation
Plug in the usb cable into your mac and start android file transfer.


Let me know if this helped or not!
