Night Shift is an optional feature that warms up the colour palette of a device's screen, particularly late in the day. It's believed that cooler (bluer) artificial light from a screen can affect a person's circadian rhythms , and Night Shift is designed to stop this happening.

See also: Night Shift was added as part of the update, so you'll need to be running that or a later version of macOS. Here's . If at any point you decide that your Mac's screen is making you feel tired or straining your eyes, you fancy a snooze in a bit etc, you can switch on Night Shift mode manually. This is very easy to do. Open the Notification Centre sidebar (if it's not open already) by clicking the icon with three dots and three lines at the very top right of your Mac's screen, or by swiping from right to left on your trackpad. Scroll up a little and two toggle switches Night Shift and Do Not Disturb will appear above the date (if you're in the Today screen) or the latest notification (if you're in the Notifications screen).

In the same section of System Preferences (Displays > Night Shift) you can adjust how radically Night Shift will alter the colour balance of your screen. Use the slider labelled 'Color Temperature' to suit your preferences. As long as you're holding down the mouse button to move the slider, the screen will change colour to give you a preview; once you let go, it will slowly fade back into the standard setting for right now, whether that's Night Shift or your conventional colour balance.
