|That's because you don't own a "Mac" (assuming x86) You own a PC running a chopped up version of UNIX. |
A real Macintosh consists of either a 68K, or PPC based machine running OS 1 - 9.22.
In order to play any legacy Macintosh games, you will have to download a Macintosh emulator and probably a system version between 7.5 - 9.22. If it's a 68K based game/emulator , 7.5 - 8.1
