Hey, I'm a noob at installing ports, and I can see you're very busy, but I get stuck in the instructions where it says "select renegade x" after "Install Software". I only get a "choose executable" option, and when I hit that, then the .exe I got from the main site, It says it has to be in the C:/ drive. So I copied it into the C drive, that I got to from the shortcut within the extracted .app… but then I can't find it? It only gives me the option to select a .exe from anywhere on my mac except the renegade.app package??? How do I into renegade? Thanks for all your help!
