Never ran.

Says it requires Mac OS X 10.6.6 or later, failed to run on two machines running 10.6.8. (Early 2006 MacBook Core Duo 2GHz, 2GB RAM, Late 2006 iMac, Core 2 Duo 1.83GHz, 1GB RAM.) Only starts to the music and the Bossa logo before presenting me with a black screen. Music plays, and the pause menu shows up. If the game doesnt support it, dont say its supported.
