Apple releases macOS 10.12.4 beta 5, and public beta will be available soon.

A few days ago Apple seeds the 5th beta of an upcoming macOS Sierra 10.12.4 update to developers, and it doesn’t have many differences from the last update except for the fixing of some small vulnerabilities and Night Shift.

First introduced on iOS devices wiht iOS 9.3, Night Shift is designed to gradually shift the display of a device from blue to yellow, cutting down on exposure to blue light, which is said to cause sleeping problems.

Additionally, Night Shift can be activated through the Displays section of System Preferences, where a setting to have it come on at sunset and turn off at sunrise is available. Night Shift can also be toggled on manually through the Notification Center or via Siri.
