I bought a Saitek ST220 Controller and it says it’s compatible with macintosh computers but i can’t seem to figure out why in medal of honor it won’t work please e-mail me if you know why.

This is the wrong forum dude.

OpenGL is a 3d graphics API, it doesnt know anything about joysticks.

You should ask that question in a forum that is related to MOHAA & Mac’s.
