    Hey guys I'm not sure if this has been asked before but I can't seem to find anything on the topic.

    Basically what I want to do is sync my Apple Cinema Display's brightness with my MacBook ambient light brightness control. So when the brightness of my MacBook changes because of ambient lighting, my secondary monitor changes with it.

    Is this possible? Is there a software that does this? This would be a great feature! Thanks in advance for everyone's input!

    While it might technically be possible to get the ambient display to work on both monitors simultaneously, the actual monitors have no idea how much relative light they are giving off compared to the other. So if each one decides to run at 25% brightness, that does not mean that both will actually be displaying at equal brightness. The best thing to do is set both to equal brightness using your eyes, not the sliders, and leave it at that.
