EDIT
So it appears that I have superuser installed on my phone. Does this mean I'm rooted? As I mention below, the rootchecker app is telling me I'm not rooted. Help!

Hi Guys,

Dumb newbie here apparently, but I can't figure out how to root my GS3 on my mac. I used the Casual application that I got from the guide, and it rebooted my phone a few times, but I don't have root, per the root checker app on my phone. The below is what the casual app did:



If I try to do it via another method I found in youtube that uses the terminal, should I first "unroot" with the Custom app? I don't want to end up bricking my phone because I've tried to do it twice. Any help is appreciated, guys! Feel really dumb- feel like this should be super easy...
