I just can't figure this out, let me explain. My father got an MSI Wind [XP for those of you who don't know], and I'm trying to figure out how to share the internet connection on my imac, because his room is too far from the router. I've tried searching for guides and whatnot on google and apple, and I've had no success. this is frustrating as it is so easy to do on windows. could anyone give me a detailed step by step guide? thanks in advance.
