Command and Conquer, Command and Conquer: Generals and its expansion pack, Command and Conquer 3 and Command and Conquer: Red Alert 3 all work on Mac. I wouldn't recommend a Mac for gaming though, you'll be very disappointed and frustrated when it comes to that.
Macs are famous only for one thing, being good computers at graphic design, however this is at best a questionable truth, as you guys may have noticed I am into the business yet me and most of my colleagues agree a PC can be as good as a Mac when it's about graphic design, I for example, do all my stuff in my PC even while I have access to Macs.
The point with Macs and Apple products in general is quite simple, they are supported by one of the best marketing programs in human history, up to the point they are now more like a religious cult than anything else.
Live well. It is the greatest revenge... And be the salt and light of Earth.

I sure hope you're not looking at the Mac Pro. The base version is $2500 with an old Intel quad core, three gigs of RAM, and a two generation old ATI 5770.
I'm not lying when I say this, you can slap together a much more capable desktop for around $600. The iMac isn't a good option either, since it uses AMDs mobile GPUs, and they start at $1200.
If building a PC isn't your thing, there's still plenty of brand name desktops that can play games much better at a better price point.
Don't turn to the dark side!
EDIT: Spelt "capable" wrong. D'oh!
One thing about C&C being on PC is that it helps provide the ability to support mods that can go along with the game.
