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 great on vintage MacBook DosDude upgrade
I have a 2009 White MacBook running High Sierra thanks to the patch utility. Everything works almost perfectly except that the brightness is a bit finicky. I encountered this after the upgrade to Sierra and solved using another utility. I upgraded to High Sierra and it appeared to fix the issue… until the latest update. Found this utility and it is really handy — I can assign keyboard shortcuts (unused F5 and F6) to adjust the brightness. Also, it remembers my last setting. So very glad to have found this utility.
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.
I miss Shades!
I have 2 monitors - the primary is dimmed nicely with this app. The 2nd monitor it has no effect whatsoever. I was using Shades on Lion and it worked beautifully on both monitors. But given the shortage of such apps available, this works better than the alternative. (I see people saying it should work on 2 monitors - is there a trick to make that work?)? I don’t have brightness option on my Mac for some reason, so this is an essential app for me - glad to find something that does work. Wish it worked better.
With Family Sharing set up, up to six family members can use this app.
