Blue light can be harsh, especially at night, or whenever you're using your Mac in a low-light setting.
For those with a Mac computer, you have the option to turn blue light off, without installing any new apps or software. You just have to know where to go to turn on the feature, known as Night Shift. You can use Night Shift on most Mac models, as long as your computer is running MacOS Sierra 10.12.4 or later.
And if you're thinking ahead, you'll also have the option to create an automated schedule for Night Shift to turn on and off by itself.
Here's how to start using the feature.

How to turn off blue light on a Mac
1. Click the Apple icon in the top-left corner of your screen.
2. Select "System Preferences."
3. Click "Displays."
4. Toggle over to the "Night Shift" section.
5. Check the box next to "Turn On Until Tomorrow" to turn it on; or you can set up a schedule by clicking into the dropdown next to "Schedule."
If you choose to schedule the Night Shift feature, you'll have the option to set it to turn on automatically from sunset to sunrise, or create a custom schedule.
If you choose the "Sunset to Sunrise" option, your computer will use your location to determine when to turn the feature on and off.
From that screen, you can also drag the slider to change the color of your screen during Night Shift. The "warmer" the screen is, the less blue light it gives off.
