Night Shift hopes to help reduce eye strain while you're working on your Mac late into the night.

Night Shift is a feature meant to help reduce eye strain during the evening hours and was first introduced by Apple on the iPhone and iPad with iOS 9.3 in 2016. Now, Night Shift is making its way to the Mac with the new macOS 10.12.4 update, which you can currently test in public beta. You'll need 10.12.4 or later to see and use this feature.

With this guide, you'll learn how to use Night Shift manually, set a schedule for it, and even control its color temperature.
