I am very new to GR (bought it yesterday) I have a Mac. I didn't see much info on the sight (maybe I'm blind) but will all these mods work on my mac? How do I install them? How do I use them? I am not much of a gamer. I like to play C&C, and SWGB occasionally with my brother. I tried GR demo from a MacAddict CD and I got hooked. I don't know a lot of the ins and outs of gaming and moding.
