Here is hoping for a Mac version though! I don't believe there have been any announcements however and Generals was ages after the PC release so it could be a long wait!
I tried the demo (should be a good indicator) on my Yonah MacBook - see sig.
I had to turn the graphics down because of the GMA 950 but it ran really smooth. I would think anyone with a dedicated video card will find it plays fine.
Ran it brilliantly through bootcamp on my core duo (not c2duo) 2ghz mbp with 1,5 gb ram. The imac shoul run it at max quality with that schnazzy nvidia card.
I doubt it, the minimum requirements call for an NVIDIA GeForce 7300GT or ATI Radeon X1600 video card or better. It further states that the GMA950 (the graphics processor in your MacBook) is not supported. 😱
