ScreenDimmer is the brightness utility Mac OSX has been missing. With support for multiple monitors, intuitive slider behavior, and always availible key shortcuts it is a simple yet comprehensive solution to a problem many Mac users struggle with.
Watching a movie on one monitor and want to dim the other? ScreenDimmer can do that. iMac screen hurting your eyes at night? ScreenDimmer can help with that too. Want to focus on your work while blocking out all other distractions? You guessed it, ScreenDimmer.
ScreenDimmer is published and maintained by me, Atlas Wegman. If you have any feedback (bug reports, feature requests, anything!) please do not hesitate to contact me.
I'll do my best to get back to you as soon as possible, and hopefully solve whatever it is you may be contacting me about!
