Apple today released macOS Sierra 10.12.4 beta 8 for developers and public beta users four days after the release of macOS Sierra 10.12.14 beta 7 for developers and about a month after launching macOS Sierra 10.12.3 and latest beta version of the future watchOS 3.2 update for developer use for testing purposes.
The secondary MacOS Sierra 10.12.4 beta update can be downloaded via the software update mechanism in the Mac App Store or via the Apple Developer Center, if you have previously installed any beta update on your Mac.
macOS Sierra 10.12.4 brings iOS Night Shift mode to Mac. Introduced on iOS devices with iOS 9.3 first, Night Shift mode is designed to gradually shift the screen of a device from blue to yellow and reduce night blue exposure. It is said that the blue light breaks the circadian rhythm and is thought to be interrupted by the sleeping order.
Night Shift can be activated from the Displays menu of System Preferences; there is a setting to turn off at sunrise and at sunrise. Night Shift can be turned on or off manually via the Notification Center or Siri. The macOS 10.12.4 update focuses mainly on Night Shift mode, but there are many enhancements under the hood.
WatchOS 3.2 beta 7 came about six months after the release of the sixth beta, and nearly two months after the release of watchOS 3.1.3. WatchOS 3.2 beta 7 can be downloaded from the General> Software Update menu using the Apple Watch application after installing the configuration profile for the iPhone. Please note that in order to be able to download the update, the Apple Watch must be connected to a charger and connected to iPhone at a charge level of at least 50%.
To install watchOS 3.2 beta requires an iPhone with iOS 10 installed and update is available for developers only. Apple does not offer watchOS for users of “Public Beta Software Program” because there is no option to downgrade in watchOS software.
WatchOS 3.2 brings innovations such as the Theater Mode, which prompts the user to quickly get the Apple Watch into view, and prevents arm movement and screen opening. With Theater Mode, users can still receive haptic-based notifications and notifications can be reached by touching the screen or using Digital Touch.
WatchOS 3.2 also adds advanced capabilities for Siri, Apple Watch. With Siri, functions such as sending messages, sending money, traveling, navigating the car, making a call, or making a photo call are now available.
