Change Displays Night Shift preferences on Mac
On your Mac, use the Night Shift pane of Displays System Preferences to shift your display to the warmer end of the colour spectrum. Warmer screen colours are easier on your eyes when you use your Mac at night or in low-light conditions.
Note: To find out if your Mac supports Night Shift, see the Apple Support article How to use Night Shift on your Mac.
To open this pane, choose Apple menu 
> System Preferences, click Displays, then click Night Shift.
