Hi, I'm new and I had SC4 for PC, but now have a mac. I've been reading around and couldn't find a clear answer to some of my questions (sorry if this sounds really stupid). But I can only download buildings from this mac BAT archive? Or is it somehow possible to download from the official STEX? And I can download any regional map? My computer only has 256 ram so should I bother with RH? Or upgrade before even playing SC4?
