iMac 3.2 GHz Intel Core i5, 8GB DDR3, Nvidia GeForce GT 755M (1GB Dedicated), running OS X 10.9.4
Tried multiple varieties of settings, as well as lower resolution and graphics and disabling features. Game is running through Steam for Mac (not beta).
Still get nothing but the black screen (after the Frictional Games Logo displays) and music. Please patch this for these newer machines

Fixed! Found the answer on a Steam community forum and was ridiculously easy. Really seems like this should be added to the locked Troubleshooting Guide post at the top of this forum.
I spent an hour reading and trying things before finding the solution elsewhere.
If you're experiencing this problem and you're running the game through Steam, right click on the game from your games list and go to Properties, then uncheck the box under the General tab for "Enable Steam Overlay in Game".
Problem solved! I know this will work for the majority of people with issues...hope it does for you!
