      5. After you get to the User Account Login screen, choose restart to bring up the the Mac in normal mode.
    d. Check "Reduce Mouse Lag" Option

    It's best to check this status of this option, as it has not worked properly for StarCraft 2 for Mac before until this patch. With this enabled, it will lower your FPS, since it's making the mouse movement smoother, for those users who may need it. It may be accidentally checked.

    The Reduce Mouse Lag option is located under Options=>Graphics.
