Here's what I sent to Apple feedback in regards to MacBookPro5,1.

I think others might find it useful, though it does not apply to Ubuntu. Ubuntu is keeping the brand high - works like a charm.

"MacBookPro Keyboard backlight controls are not intuitive."


I thought it was broken for 2 weeks. I tried all remedies I could think of. I finally called technical support. And I learned that it is so "by design". Bad design that is.

Ok, here's the deal. When I press keyboard buttons that are supposed to control keyboard backlight, I get the keyboard light popup (onscreen display) with single-crossed circle which I understand as "not working", and the light does not change. However the change in ambient light does adjust the keyboard backlight. If I uncheck "Illuminate keyboard in low light conditions", the buttons still do not work unless it is dark enough in the room.

1. It is a usability issue. I want to have control over keyboard backlight in well-lit room, but I don't have it

2. When I disable automatic control, I want full manual control, but I don't get it.

3. The indication on display is not intuitive and misleading. There is no explanation in help files what it means. The sign may mean many things including "your hardware is broken".

4. The function is not consistent with display backlight control. I can always adjust the display backlight, even if it is dimmed or brightened by automatic control. But the keyboard backlight follows different concept. And the concept is alien to Apple.

Issue applies to:
  • Mac OS X version is 10.5.6.
  • Same in Windows XP + bootCamp drivers


Works great in Ubuntu Intrepid
