If however you are referring to the fact it does display an image but the Touch screen capability does not work, then this is almost certainly because your Mac does not (at this point) have the right software drivers installed to enable this capability. When you say it does not work, what do you mean? Do you mean no video appears? If so you need to connec tthe monitor to the Mac via VGA, or DVI, or HDMI, or Displayport, etc.
Any other computer with Windows works fine with this USB wire.
I use USB wire which was together with monitor.
