I have a late 2009 macbook, and before updating to osx mavericks (from mountain lion) i was able to play halo ce, and the game ran smoothly. but after updating to mavericks, the game defaulted the display settings to have 0 hz refresh rate, and the framerate went down to

30 fps (and the game won't let me change either of those settings...), and now the game lags A LOT, but before updating, the game ran at 60 hz refresh rate, and the frame rate was 30 fps. does anyone else have this problem? does anyone know a fix?
