Well I gat back from work and gave it a run. For the most part it runs just fine, graphics display and the sound clip plays too without any popup errors. However the one bug I found was that most of the faces were showing a block of glitchy and random static instead of their respective sprite. Here is a couple of screenies to show basically what it was doing.
Go ahead and send me an update or tweaked version if you like. I can be your 'real test run' on the current iMacs if you like.
My system specs are:
CPU: Intel Core i7 (Quad Core)
GPU: ATI Radeon HD 4850
Screen Res: 2560 x 1440 (27" screen)
RAM: 4GB DDR3
OS: Mac OS X 10.6.4
