Apple released the sixth test update of macOS 10.12.4 Beta 6 and iOS 10.3 Beta 6 in the early morning, including developer testing and public version testing.

IOS 10.3 is the third major version update of iOS 10 system. IOS 10.3 also contains many new functions. The main function is "Find AirPods", which is Apple's official tool to prevent users from losing AirPods. In addition to "Find AirPods", there are also map updates, new weather forecasts, Siri improvements, Uber payments or subscriptions, and HomeKit and CarPlay improvements.

The MacOS 10.12.4 Beta6 update adds the Night Shift function that previously existed in iOS 9.3. The blue light filtered on the screen will emit warm yellow, which can protect your eyes and help you fall asleep quickly. Previously, only iOS users could experience this function, but now it can be used on the latest version of Mac.
