As many of you have noted here, Civ IV base game and Colonization are currently not working in 10.10 due to a python library issue.

After a week of review, this bug is legitimate and we are now officially pulling support for Yosemite until we have a fix for the problem.

Please accept our apology for any frustration this bug has caused. We are working on a solution, but because of the hectic holiday release schedule from Aspyr, we cant give an approximate date as to when that solution will be integrated into the game.

There is a workaround (users have posted it in several spots). It works 100%, but we should advise strong caution when messing with your library files. Make sure you backup your rig with time machine before diving in.

Please let me know if anyone has any questions, and again apologies for the interruption in play on a GREAT game.

UPDATE: A fix is now live. Support now goes back all the way to 10.6. Thanks to everyone for their patience and support.

I should also note that some users are having success by making sure that Warlords and/or Beyond the Sword are installed on top of the base Civ IV game.

The patch that replaces GameSpy with Steamworks for multiplayer functionality is now available via Steam. The game functions identically to the previous GameSpy version with the exception that the “Direct IP” option has been removed as it is no longer supported. Save game data should not be negatively affected. If you own a physical disc version of Civilization IV and are interested in receiving this multiplayer update, please submit a support request. http://support.2k.com/requests/new
