Ok so I've heard that Counter Strike Source runs just fine on the MacBook, so I decided to give it a try. After finally downloading it though, I have a problem stopping me from playing. After the loading screen starts up, the screen turns black. It's still actually running, because when I scroll the mouse around I can hear the menu options clicking when I hover over. Any idea what that could be? My only assumption is perhaps the RAM...but I dunno how that could be...so any suggestions would help greatly. Thanks.
