How to Use Night Shift in macOS Sierra
If you're having trouble sleeping, and wondering if constant exposure to your MacBook is to blame, you might want to download macOS Sierra 10.12.4. This update includes the Night Shift feature, seen previously in iOS, which is meant to help users get better rest at night.
Just as with Night Shift on iOS and Night Light in Windows 10, Night Shift makes your Mac's display emit a warmer range of colors, removing blue light. This became a popular feature after studies showed that exposure to blue light wavelengths makes it harder to fall asleep by increasing attention and reaction times, as well as altering your mood.
And on macOS (as it works on iOS) Night Shift can either be enabled manually or scheduled to automatically activate at night. Here's how to use Night Shift on macOS:
How to schedule Night Shift mode:
1. Click the Apple icon in the top left corner.
2. Select System Preferences.
3. Click Displays.
4. Select Night Shift.
5. Click Off.
6. Select Sunset to Sunrise. If you sleep during different hours and want Night Shift to operate on a different schedule, select Custom and enter those times.
You've enabled Night Shift! If the display looks too warm or cold, adjust the Color Temperature slider accordingly.
How to manually enable Night Shift mode:
1. Click the Notification Center icon in the top right corner.
2. Scroll up.
3. Turn on the Night Shift switch.
You've enabled Night Shift. Now get some rest!
