Anybody have any idea? 
 
It looks like Civ IV has -- has anyone played it? Are there performance issues?

I played civ4 on a mac and it was ok. It ran fine. I would love civ5 to come to mac cause then i could well play it on my mac.

Every Civ eventually also come out on the Mac. Usually a year or a year and a half later. Performance was ok, but always worse than under BootCamp.

here is a post on the 2k forums for an unofficial way to get it to run on a Mac

...if iI get it now, will it work with SteamPlay?  I'm not paying for this twice.

First Report: Managed to get some kind of black screen of the Demo, running in DX9. Including the Civ 5 cursor. Not much more though.. more to follow!

DO IT!
DO IT NOW!

I'd be interested in getting Civ IV for my Mac, is there any Mac equivalent of Will It Run? I've literally never tried to play anything more advanced than flash games on here.

So I just downloaded the Civ IV demo and it said that my system was below minimum requirements. How is that even possible when I bought the machine in 2008 and the game came out in 2005?

I'd prefer to play it on a mac, since I hate having to reboot to play certain games (oh thank you Steam, now please gimme L4D2 mac!), but I don'T think I'm patient enough to do so. At least when it DOES come to mac, it'll surely be Steam Play, everything else so far has been. I don't think valve lets you have a separate mac version. Probably why not every single game has made the jump, since it's pretty easy to make a PC game work on a mac these days.

I live in fear of the day this comes out on Mac. The Civilization series is an albatross upon my soul. I've been able to break free of its dark gravity at times, but the recidivism rate is HIGH.

I have a Macbook Pro with 9400M/9600M and I got Civ 5 to run with the SteamPC app mentioned on 2k forums. I had to set terrain overlay to Medium (to avoid a gray map) and everything else to Low, but the performance is still... not great, when you get into the late game with lots of cities and units. I had to frequently switch to the strategic 2D view because zooming to another unit would turn into a horrible slideshow - good thing the option exists. Surprisingly it ran even slightly worse when I switched to 9600M.

I'd love to hear some performance comparisons between the Wine/Crossover method, VMWare/Parallels and native Bootcamp.

I have a 2010 Macbok Pro 17" and it runs great on Boot Camp. i7, GT 330M.

Throwing out some more data points... I gave Parallels Desktop 6 a shot (using the trial version), and the performance is even worse than with Wine/Crossover. I loaded the endgame quicksave and it was practically unplayable in the regular 3D view. So, I gave up and made a Boot Camp XP partition; now Civ runs beautifully. I have a mix of Medium/Low settings and everything was smooth at least up to late Renaissance Era. I didn't try to go any higher because the graphics are already good enough for me and I like smoothness. Guess I'll have to do with the dedicated Civ partition until they release the Mac version.
