I was asked to download quite a few maps from the One X Alliance clan site but when i click on the file to download to my mac, my mac says it does not know how to handle the file and what file do i want to use to open it. I guess i have to name the file or call it something dont i? Any recomendations on how i go about this one because i need those maps. And will these files once in the map folder work on the mac.?
