so i recently downloaded cs:source off steam on my macbook (see sig for specs). When i loaded it up i got those two guys with loading in the bottom right. then i got a black screen. i eventually figured out what it was. it was the menu and stuff just i couldn't see it. like i heard the clicking and stuff just all black (and some white boxes that would pop up after i clicked too much). anyways - has this happened to anyone else and if so do you know how to fix it? i was fooling around with it and after a little while of pressing random keys a game popped up and i played but that only happened once out of like 100 tries. also whenever i load the game it goes into full screen. maybe putting it in a window would mak it run better? how would i do that too? please help.
