Mac problems

[CLETUS]

Hi I play CSS and I have a mac. Sometimes when I try and download a map it says missing map. So then i try and download it off of gamebanana or something of the sort. But then it comes out as a .rar or something file adn i cannot extract it to become a .bsp file. Is there anyway to extract a file on a mac and make it a .bsp? HALP!

I think this should do it.
