Hi I downloaded and started up the episode 2 on OSX steam, and it seems like there is a graphical glitch that make half of the body disappear from the characters (they look like zombies). Yes my system meets the requirement. I played the episode one with high settings on native resolution with 30 fps+. Also I verified (repaired) cache files on steam. ALSO I did a reboot and reinstalled the game. None of them worked. I'll also post a video of the issue if that helps.
