Apple has begun rolling out macOS 10.12.4 to the public today. The update is available for supported Macs via the Mac App Store. The latest version brings NightShift to the Mac.
While NightShift is the biggest features, the update also has some smaller updates to Siri, Dictation, and more.
- Night Shift now available on the Mac.
- Dictation support for Shanghainese.
- Ask Siri about cricket scores, schedules and player rosters. Siri knows about statistics and data from the Indian Premier League and International Cricket Council.
- Updated PDFKit APIs for better displaying of PDFs in apps that use the framework.
This is how Apple describes NightShift:
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.
