Reducing Mac screen brightness even further
While I generally love my iMac, one thing I always hated from the first day was the insufficient range within which you can regulate the screen brightness.
Especially at night when the surroundings are dark, even the lowest setting is still too bright and both illuminates the whole room and also hurts the eyes after a while.
Today I found a simple tool with the even simpler name Brightness Control that allows you to tune down the screen backlight brightness in a much wider range than the built-in Mac OS brightness control. Unfortunately you cannot have it disappear completely - its icon will stay in the dock while running - but this a small price for the added comfort.
