Mac Lag

[GriffinFR]

So i bought The Cave the other day and it was giving me some strange lad issues. First of all, at the main menu it takes a few seconds for the game to register me scrolling the options with my mouse. At random moments subtitles aren't in sync with the dialouge and here comes the most annoying part, my characters controls lag HARD. I'm not sure why it does this but maybe it could have something to do with my mac? all my other games work fine but the cave lags really bad. if anyonehas any ideas as to how to fix it, i really could use the help
