By all means the brightness settings on Mac OS X are great but Dimmer allows that extra depth of brightness. This is a great application to use when you find the lowest display setting is too dark and the second lowest display setting is slightly too bright.
Dimmer was created and tested on a Macbook Pro running OS X 10.5.8 (Leopard). I am not sure specifically which versions Dimmer will work with apart from 10.5. 10.4 (Tiger) should be okay and 10.6 (Snow Leopard) shouldn't have any problems either. If you do find bugs then more...
