After releasing macOS Sierra 10.12.3 three days ago and the first 10.12.4 beta to developers, two days ago, Apple has returned with the first beta of macOS Sierra 10.12.4 update that’s now available to public testers. Night Shift mode is the new feature that will help Mac users stay up late without exhausting their eyes.
Apple has a beta testing program and users who registered are allowed to download the 10.12.4 macOS Sierra beta from the Mac App Store, through the Software Update mechanism. In order to sign up for Apple’s beta testing program users will need to login using their Apple ID and password, but after they get “inside”, they have access to all iOS and macOS Sierra betas. However, they are advised to not install these betas on a primary machine, because they’re unstable and could damage iPhones, iPads and Macs, respectively.
The new macOS Sierra 10.12.4 public beta that was just released comes with Night Shift, a popular feature that will cut down blue light exposure, so that Mac users will go to bed without having problems falling asleep. It is known that the blue light is very harmful to eyes and affects vision, and the yellow light is preferable, as it causes less damage.
If users turn on Night Shift mode, their Mac’s screen will automatically shift from cool to warm when the sun goes down, as the feature will use the device’s clock, and combined with geolocation, it will determine when the sun sets in that location. And when the sun comes up again, the screen is back to its normal colors.
However, users can set custom times when they want the display’s colors to shift, and they can toggle the effect on manually. If they will go to the Notification Center, they will find the toggle to turn Night Shift mode on, but they can also tell Siri to activate it. Other new features introduced in macOS Sierra 10.12.4 are Shanghainese dictation support and cricket scores for Siri, alongside PDFKit improvements.
