Longtime Mac users know all about the wonders of f.lux, a third-party system preference that automatically adjusts your screen’s color temperature, shifting it from blue to yellow throughout the day in order to combat the harmful effects of blue light.
With iOS 9.3, Apple added a feature called “Night Shift” that’s essentially f.lux, but for your iPhone or iPad. The useful feature is now headed to the Mac.
The latest developer beta for macOS Sierra version 10.4.1 beta 1, includes a Night Shift mode. How it works is unclear (we’re working on installing the new version), but we wouldn’t be surprised if it works much like f.lux.
Mind you, the feature is only available through the developer beta and not the public beta, each of which is available through the Apple Developer Center. A public beta release, however, shouldn’t be too far off.
While not definitive, there’s been a good amount of research that links the blue light emitted from screens to eye strain and sleep disruption. Many people who have installed f.lux have credited it with helping their eyes feel less tired and improving their sleep.
It’s not just makers of devices with screens on them that are taking notice. At CES 2017, Soraa debuted its Helia smart light bulbs for the home that gradually shift the color temperature from blue light in the morning to warmer, yellower light at night.
Adding Night Shift to macOS isn’t just another case of an iOS feature making the jump from iPhone to the Mac, but another way Apple’s doubling down on health and well-being, an area CEO Tim Cook and his squad have prioritized.
