Amnesia:TDD Infinite Black Screen and Sound

[ThornsNRosez]

So, I downloaded Amnesia: The Dark Descent from Steam the other day and I've had nothing but problems.
When I run it on fullscreen it simply freezes my computer.
When I run it in a window, I get the "Frictional Games" logo to flash for a moment and then it loads silently on a black screen for a moment and then I get the background music and black screen forever. Nothing ever loads, no menus, no outlines or anything. Just music.

I Verified the Integrity of Game Cache on Steam, with no problems.

I have a Macbook Pro 15". Amnesia is running on my NVIDIA card. And I tried to follow the graphics card stuff to check out from the pathway Library/Application Support/ but there is nothing for Frictional Games on here...

I am just beyond confused at this point.
