Hi there Esther,, I have an I Mac with a normal Apple wireless keyboard. Whether I'm in the Display control panel and turn the brightness to zero, or move up and down the brightness scale with F14 and F15, nothing seems to happen.
The screen curtain works fine turning my screen totally dark. There is no sensor on the I Mac so, I assume, there is no automatic brightness selection option. Any ideas?
