I have a Mac with two monitors. When I start VO, the second one goes blank/dark. Anyone have any success in getting a setup like this to work?

Try setting your game to "windowed" mode in the video settings... I have a mac with dual monitor as well and this was the only solution... cant be in full screen on one screen and have say Safari up on the other.. unfortunate, i know. Apparently some games do support that ability though with a "full screen window" mode.

PS: I tried searching for a 3rd party software that would allow you to do this.. but had no luck..
