Game freezes when playing Opening Cinema and Ul'dah Airship Cinema

I'm playing on a dual-booted Macbook Pro. Whenever I attempt to launch the game and the opening cinema automatically begins to play, my screen goes completely black and nothing plays. It just hangs there. I was able to get around this by editing the FFXIV.cfg file under MyGame>SquareEnix folder and setting CutsceneMovieOpening to 1. However the problem seems to have reared it's head once again whenever I try to take the airship from Ul'dah. The in game cutscene plays just fine but then goes completely black and nothing happens. Not sure what's causing this issue but it's preventing me from playing the game completely anymore.
