Research suggests that exposure to blue light fools your body into thinking it’s daytime, making it harder to fall asleep if you work late on a Mac with a bright white (which has a lot of blue light) screen. To help, a macOS feature called Night Shift subtly changes the screen’s colours as the sun sets to reduce the amount of blue light hitting your eyes. In essence, everything gets slightly warmer. To configure your Night Shift schedule—so it turns on and off automatically—go to System Settings > Displays > Night Shift. You can set any time, but Sunset to Sunrise adjusts for the sun’s movement in your location throughout the year. One warning: if you edit photos or videos or work on graphics where specific colours matter, Night Shift’s colour changes may be problematic.
