So I just recently downloaded a version of Grim Fandango onto my macbook. However it won't run and so I need to figure out a way to convert it from pc to mac. I know nothing about computers nor do I have any idea where to start with this type of thing. I just loved this game as a kid and wanted to try it again. Any suggestions on where to start? I apologize for this being so vague. The files are in .nrg form it says. I'm useless.
