Apple has finally rolled out Night Shift on the newest update to macOS Sierra. Night Shift is a program that gradually removes the blue light of your display to help relieve eye strain and help you sleep better. A similar program, f.lux, has been available cross-platform for a while now, but Apple decided to include a similar software on iOS and now macOS. Check your Mac for update 10.12.4 if you are looking forward to this feature for your desktop.
