I want to preface that I know next to nothing about computers, I watch youtube and search stuff on google, but other than that I am clueless. So I am trying to play Team Fortress 2 on my Apple PowerBook G4 550 on Steam. I launch the game and it gives me this message:
Error Could not find required OpenGL entry point 'glGetError'! Either your video card in unsupported, or your OpenGL driver needs to be updated.
I haven't the foggiest idea what this means, so any help would be appreciated.
