Message: Quit Unexpectedly but I have a GMA X3100

[Urkle]

You would at minimum need to upgrade to snow leopard to get the newer OpenGL API (think of it like direct x versions on windows) on that hardware. Given the history of the intel graphics hardware though, I doubt it'll work even then. ( you may get lucky though).

And of course getting a new Mac would definitely solve the issue, as Apple dropped the intel graphics cards in all models for the past few years. Also many other game develops explicitly do not support the intel graphics cards on Mac due to the poor drivers available.
