@Unownshipper:

You can't launch a private match without one other player on mac? I can tell you that's not the case on PC, but Steam supports the multiplayer matches by itself so that's probably why.

That said, if anyone finds a way to take HUD-free screenshots (better ask JLBiggs about that, he will surely answer how), I can help by posing as model with each characters in private matches, but only on PC.
