Yes, it does. Don't use the USB DMX, make sure it's a pro. You can also use the Enttec DMX Ethergate MK2 (I prefer this one because I can also use it for PixelMAD).
Oh and someone who has used the hell out of Arkaos, I'll warn you. Make sure to create a new Tiger (yes Tiger not Leopard) boot partition. It doesn't have to be big, 20Gb is fine. There are conflicts with Catalyst on a system that previously had Arkaos on the same partition. You would think it doesn't matter but trust me, it did on a few occations for me.
