With Brightness Slider you can adjust screen brightness from the menu
bar, just like the sound menu provided by Apple, and with improved
control over the dimming process.
Using a keyboard with no brightness keys? Tired of low brightness
levels which are still too bright? Brightness Slider gives you total
control over your screen's brightness settings, allowing in
particular for a really smooth transition between low light and total
- Screen brightness level adjustment right from the menu bar
- Dimming control at low brightness levels
- Arrow key function with active Brightness Slider menu
- Custom hotkeys for lowering and raising brightness levels
- Start at login option available in the preferences
How Brightness Slider works:
Brightness Slider darkens your display by combining two separate
methods. Method A adjusts the real backlight intensity of your
display and method B creates a semi-transparent black veil above
everything else. Why the complexity? Well, when dimming a display,
the final jump down to no backlight at all is very large, especially
in a darkened room. To provide more control over the dimming process,
the top-half of the slider controls the backlight intensity from 1
down to 0.1 (method A). Then, the bottom-half controls the opacity of
the semi-transparent veil, whilst keeping the backlight at 0.1
(method B). When the slider is at zero, the backlight is turned off.
The result is that the final jump now has several intermediate steps,
which means the perceived brightness (the combined result of both
methods) is that much more adjustable.
One last thing:
There are displays where Brightness Slider cannot control backlight
intensity. However, it can still perceptually dim the screen by
controlling the opacity of the semi-transparent veil (which can be
created on any display).

Works Perfectly! - Works amazingly well, especially for being free. The mouse stays at the default brightness so you never lose it even at the minimum brightness! Would recommend.
Activates discrete graphics - While this is great for desktops and always-plugged-in laptops, for those of us who don't have a charger ALL the time this isn't worth it. It activates your discrete graphics card and battery life plummets.

Doesn’t dim both monitors - Only dims main monitor, so this is useless to anyone with multiple monitors unless you one want to dim one, which I can’t see as a common use case.
Overthought - It’s a clever trick, first turning down the native backlight and then overlaying a semitransparent veil. The problem is it means the point where that break happens has to be hard coded, and since no program can adjust the backlight of a non-Apple external display, the dimming effect will always be incongruous between your internal and external displays. Also, as others have noted, a bug: I have two external displays, but this only dims one of them.
Not consistent across all monitors - The first fifty percent of the slider dims the apple display backlight (having no effect on external displays). Then, the lower fifty percent apply a “veil” of gray (by manipulating the color output). This works on all monitors. However , the native apple display birghtness has already been turned all the way down, then further. So on the lower half, the apple screen is darker than the other external monitors. And when turned all the way up, the paple display is exceedingly bright compared to the others. There should be the option to control each kind of dimming separately. With all the different types of monitors and setups, giving users more control to adapt to their situation is most appropriate. Kudos for trying to make a simple interface but it needs a little more thought on the settings configuration.
It works, but not for dual displays - It will dim your main display, but not a second display. It kind of defeats the point of the app to have one dimmed and the other still burning out your retinas.
THANK YOU!!! - I’m using an ultrawide AOC monitor with my macbook pro, along with a mechanical keyboard that is not manufactured by Apple either. This app works PERFECTLY with my monitor and I am now not only able to control the brightness from the new convenient menu bar slider, but using the preferences settings in this app, I was also able to map brightness up and brightness down to two function keys on my non-Apple keyboard! I’M SO HAPPY! THANK YOU!
