    Under System preferences - Displays - there is a new slider Ambient Light Compensation.

    Do you know what is it supposed to be doing?
    I haven't seen that slider ever.

    I can't see this slider on my MacBook Pro 8,1. Retina only maybe?

    The extra setting, a checkbox not a slider, is present on my 13" rMBP. I don't think it's been implemented yet.

    My mistake. Checkbox not slider. But yes it's there - I enabled it and I don't see any changes.
    Could be a f.lux equivalent?...

    It changes the hue much like f.lux. If you're in a room with incandescent ("orangish") bulbs, or any area without sunlight (which has more of a "blue" tone), turn it on. Let it be for a few minutes as it slowly changes the hue. Then, after a few minutes or so, go back and uncheck it. You should see a difference so long as you're in an area where it can match the ambient light correctly.

    I just installed 10.11 on my 2008 MacBook Air and you're right, the checkbox isn't there either.
    So you're saying it's already implemented? I'll leave it on for a while then.

    It's hard to tell to what degree the hues change. However, f.lux changes based upon time of day to match the sunrise or sunset, in addition to the ambient lighting (which you have to set manually in f.lux), in order to assist with your circadian rhythm.

    I'm not so sure this would be a f.lux replacement, as it appears to only match your display to ambient lighting in order to give you the best color representation that it can. f.lux's entire reason for existence is the opposite of this.

    Apple's ambient lighting: seems to be to ensure proper display of colors / color perception.
    f.lux: assists your circadian rhythm by modifying the display hues to simulate day or night.
