Was looking at the Mac page of the Steam Store, and I saw this:
 

I wonder if its more stable than playing on Windows XP Bootcamp.

Doubt that. Civ4 was worse native, than on BootCamp.

I played it all day yesterday and it ran like a dream. "

It runs like god damn shit on my 9400M in OSX but runs fine in Bootcamp. 

It run's pretty crappy on my macbook :(

The Mac finally has more than five games in it's libary.

I was wondering the other day why civ 5 was relisted under new releases. Grats to you crazy mac kids I guess.

Very happy that its on steamplay, made the gamble and bought it pre-order on windows, now it plays plays just as well on the MBP where ever I am. 
 
 Can't seem to save to the steamcloud though, don't remember if I could on the PC. :S

Anyone know if this would run on my 3 year old Macbook Pro?  It doesn't need to run great, just be playable.

the real question here for us mac owners is. Is it worth it to keep playing games on mac or should we just get a damn gaming pc if we're really serious about this. I've been trying to play sc2 on bootcamp for a while and let me tell yu it's painful to have to play on low setting and still get framerate problems in multiplayer.

Doesn't look like there is a mac demo planned, that sucks.

Can You play against a PC owner? I have a friend with a mac that I'd like to play against. 

Not at the moment, you can't. The multiplayer lobby will kick the guest from the lobby, saying there's a difference in versions. It's an error, and Firaxis has said, I believe, that they intend to fix it.

Ughh I really want to get this, but I just keep hearing about how bad the mac port is. 

Mac port is pretty solid from my experience, on my iMac it runs just as well on maxed settings as it did on bootcamp.  Pretty much no real reason for me to boot into bootcamp anymore these days, with all the stuff I want to play having mac versions made. 
 
If your system is lower-end, you may run into a problem.  But with a decent iMac or something, should be no problem.

Played an illegal Windows port for Mac to test it out and that ran smooth so I immediately bought the official Civ 5 on Steam yesterday. I've been playing happily ever since. I'm playing on my mid 2007 iMac wich has the exact minimum requirements. 2,4ghz, 2600HD video card but I do have 4 gigs of RAM (Original had 1GB I think). It's been running great so far but my only general problem with all these Mac ports is that they lack features. I can't install mods or download the DLC. I would love to do so but we get a version cut off from the bigger community. It's a big step forward and I know that I can always just go to Boot Camp and play the DLC there. But Civ is the kinda game I played windowed while listening to a podcast and browsing the web in between some turns. It's an amazing timesink and it's my first foray into 'real' Civs as my first time was Civ Rev. 
 
imo: Worth the buy, if you have the minimum requirements it runs smooth as butter on the lower settings but there will be a bit of slowdown during the final turns. It really isn't that big of a deal imo. Small tip: If the 'fog of war' just consists of grey blocks turn it up from minimum to low and that problem will be fixed :) Looooove this game.
