Use Night Shift on Mac
Use Night Shift to adjust the colours on your display to the warmer end of the colour spectrum. Warm screen colours are easier on your eyes when you use your Mac at night or in low-light conditions. Also, exposure to bright blue light in the evening can make it harder to fall asleep.
Note: To find out if your Mac supports Night Shift, see the Apple Support article Use Night Shift on your Mac.
Schedule Night Shift to turn on automatically
On your Mac, choose Apple menu
> System Preferences, click Displays, then click Night Shift.Click the Schedule pop-up menu, then choose an option.
Off: Choose this if you don’t want Night Shift to come on automatically.
Custom: Choose this to specify the times you want Night Shift to turn on and off.
Sunset to Sunrise: Choose this to use Night Shift from sunset to sunrise.
If you select this option, your Mac uses your location to determine when it’s nighttime for you. To use this option, you must turn on Location Services. Choose Apple menu > System Preferences, click Security & Privacy, then click Privacy. Select Location Services, click the lock to allow changes, then click Enable Location Services, scroll down to System Services, click Details, select Time Zone & System Customisation, then click Done.
