macOS Sierra 10.12.4 brings iOS's Night Shift mode to the Mac for the first time. Night Shift, first introduced on iOS devices in iOS 9.3, is designed to gradually shift the display of a device from blue to a subtle yellow, cutting down on exposure to blue light. Blue light is believed to interrupt the circadian rhythm, disrupting sleep patterns.

Night Shift is activated through the Displays section of System Preferences, where a setting to have it come on at sunset and turn off at sunrise is available. It can also be set to turn on and off at custom times. Night Shift can also be toggled on manually using the Notification Center or Siri.

Night Shift was introduced in macOS Sierra 10.12.4 (16E144f) and is controlled by the CoreBrightness.framework. 
The official minimum requirements for this feature are: 

- MacBookPro9,x
- iMac13,x
- Macmini6,x
- MacBookAir5,x
- MacPro6,x
- MacBook8,x

Of course, this patch is intended to bypass this check completely.

Why We Want It

"Many Studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep. Night Shift uses your Macs clock and geolocation to determine when it's sunlight in your location, then it automatically shifts the colors in your display to the warmer end of the spectrum. In the morning, it returns the display to its regular settings. Pleasant dreams"



Rather than using a third-party option such as f.lux, you can make use of Apple high quality default Display Function. This Shell Script enables the feature for all Macs

Open Source / Upgradable

This script is completely open source (via Pike’s request) and changes can be made on a instant if needed. This is because the script and a copy of the framework is in the GitHub Repository.


The script is built with simplicity in mind. The terminal commands are easily identified both within the file and when in progress.


This script will replace the CoreBrightness.framework with one already patched with the matching hex value in CoreBrightness.framework for most older/unsupported hardware.
