Black screen

[solasolsi]

Hi everyone,

You will excuse me if my english isn't perfect, i had bough the game recently and i've being unable to access to the game.

The program is "starting" i can see the logo of Frictional Games but right after that i can hear the "creepy sound" which should be playing on the game menu screen but everything on the screen is black.

Hope you will be able to help me cause i dont think it could be possible to have a problem with my iMac. (every other programs are running fine and fluid)

3,4 GHz Intel Core i7
16 Go 1600 MHz DDR3
NVIDIA GeForce GTX 680MX 2048 Mo
OS X Maverick 10.9

Waiting for your answer, and thanks in advance.

(and btw i've already tried to remove cfg file, disable SSAO, putting all setting to low, disable fullscreen.)
