Totally frustrated...Im able to download both Boxer and MoM, but Boxer won't run the game! It says that since MoM is a EXE file that it doesn't recognize it--am I doing something wrong? Or is there another program I need to download?

I'm unfamiliar with Boxer but MoM is a DOS game so you should be able to run it using the Mac version of DosBox. The difficult part would be to get GoG's install program to run on a Mac.

Yeah you have to install the game on a Windows machine and copy and paste the installed folder to your Mac. Then it will run in Boxer no problem.
