What’s new in macOS Sierra 10.12.4

Night Shift Mode, introduced on iPhone with iOS 9, is coming to your Mac courtesy of Sierra’s upcoming software update, the fourth major update since Sierra’s debut last fall. Night Shift was designed to help users adjust the temperature of their computer’s display from cool to warm, either manually or based on the time of day.

You can access Night Shift in System Preferences, Notification Center or via Siri.

Using a dedicated Night Shift preference pane, you can adjust options to allow your Mac’s display to gradually shift from blue to yellow and cut down on exposure to blue light, which is said to cause sleeping problems.

Aside from Night Shift, macOS Sierra 10.12.4 brings Dictation support for Shanghainese, an updated PDF API fixing a few annoying bugs, iCloud Analytics options and the ability for Siri to look up Cricket schedules, scores and rosters for two new cricket leagues.

And of course, the macOS Sierra 10.12.4 update “improves the stability, compatibility and security of your Mac,” according to Apple’s official release notes.
