macOS Sierra’s long-awaited ‘Night Shift’ feature is here today

Apple today is rolling out macOS 10.12.4 through the Mac App Store. The latest version of macOS Sierra brings a handful of cool upgrades, but none as exciting as ‘Night Shift,’ the long-awaited app we first fell in love with on iOS.

Here’s how Apple describes the new feature:

Night Shift adjusts the color of your display after sunset. Many studies show that exposure to bright-blue light in the evening can affect your circadian rhythms and make it harder to fall asleep. After sunset, Night Shift will shift your display colors to the warmer end of the spectrum, making the display easier on your eyes. In the morning, your display returns to its regular settings.

If you’re a past F.lux user — or current Windows user — this may all sound familiar to you. 10.12.4 is the first version of macOS Sierra, however, to bring it to Mac users without third-party apps.

Aside from Night Shift, 10.12.4 also brings updates to Siri, Dictation, and PDFKit APIs.
