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).

Allows you to reduce past the Apple Minimum Brightness

On my iPhone I often turn on the “Reduce White Point” setting which makes it a lot easier to look at the screen in a dark room without hurting my eyes.

This app allows brightness dimming further than the normal minimum brightness, just like with “Reduce White Point”! Perfect for anyone who uses their Mac at night or in dark places and just needs to reduce the strain on their eyes! Excellent app thank you!

Great replacement for 2011 MBP’s with discrete GPU issue

This app is perfect if you have had to disable the discrete GPU for any reason in your laptop such as with the early 2011 MacBook Pro’s as this can affect the ability to adjust brightness at all leaving the monitor on full brightness as default. I have just set the shortcut keys to use Function and F1 and the same for F2 to get the ability to reduce and increase brighness to match the default function keys as much as possible. Great app :-))

imac and high Sierra

I’m running high sierra on an iMac and after a software upgrade my brightness function ceased to work, raising it briefly for a second ond then returning to low, although on screen indicator showed it as having increased. This tidy app has given me back this function, after many hours trying to rectify the original malfunction.
