I'm having an issue with the graphics on the mac version of the game. I get flickering graphics on the top half of the screen, with corrupted visuals near the top. There's a solution for this on the PC version, but the fix only runs as a .exe so I can't use that. Does anyone know how to fix this? I'm using a 2011 Macbook Pro.

I have this same problem with corrupted visuals on a 2010 Macbook Pro. If anyone knows a fix for the problem it would be really appreciated!

got the same error running the game on early 2009 mac mini with mountain lion. The game is unplayable.

Same for me :(

Macbook unibody 2009 on OSX Mavericks.

i've installed xquartz to replace X11 like apple support ask but doesn't work.

I uninstall him to the same result.

The solution in THIS POST by user Aichonic worked for me :)!

Edit : successed step 2, it's work !
