- Use Night Shift on Mac. Use Night Shift to adjust the colors on your display to the warmer end of the color spectrum. Warm screen colors are easier on your eyes when you use your Mac at night or in low-light conditions. And exposure to bright blue light in the evening can make it harder to fall asleep.
- I'm using Mac OS Sierra on an 11 inch Macbook Air, using an external Acer 24 inch monitor. I would like Night Shift to be always on. In system preferences - displays - Acer G236HL - the Night Shift tab, here's a picture of the settings: The closest way to getting what I want is to check 'Turn on until tomorrow', which works as expected.
Mac OS X has also introduced the Night Shift feature which is nothing but the blue light filter. The function of the night shift is basically to turn on the blue light filter on the operating system and help improve sleep of users who use PC till late night. Almost all major operating system platforms have included the blue light filter in their ecosystems.
What is this blue light filter? Computer or mobile screens have a bluish hue in their back light. After several years of exhaustive research, scientists from different parts of the world have found out that blue light disturbs sleep by hyper activating the eyes and the nervous system. This is one reason why why can not sleep even if we are tired. The blue light has been found to stimulate nerves and the brain simultaneously and deprives sleep. Since, health is the biggest priority of human life, every gadget manufacturing company have started using blue light filter software in their devices.
When the blue light filter is turned on, a reddish hue filter is applied on the back light and the overall color warmth is increased to some extent. Blue light filters have been found to improve sleep to a good extent. You can turn on Night Shift mode on Mac OS X whenever you require. You can also schedule the time stamps when the night shift mode will turn on or off.
Steps To Enable Night Shift On Mac OS X
1. First of all, tap on Apple icon. Now click About this Mac.
2. Now, the Macintosh HD opens. Click on the Display tab. When the storage is being calculated, you can simply tap on Manage option.
3. Next, click on Display Preferences. Check the above image for reference.
4. As the Built-in Retina display preferences open, you will find the Night shift mode. You can choose the schedule menu, if you want to schedule the turning on or off of the night shift. You can also set manual timestamps and even specify the color warmth to be applied during night shift. Once, you are done, click on
One of the downsides of using a computer, or any device with a screen, is the effect it can have on both our eyes and our circadian rhythms. While eye damage is unlikely and eye strain somewhat contentious there’s much more research that shows the effect of certain colors of light on our brains at different times of the day.
The blue-ish light emitted by most computer and mobile device displays can cause tired eyes to struggle at night, and it fools our brain into thinking it’s daytime, even when it’s late at night. The solution Apple has come up with is to allow displays on its Macs and iOS devices to shift color automatically at certain times of the day. The screen goes from blue-ish color during the day to warmer more yellow tones in the late evening. That yellowish color is supposed to take less effort to view on the part of our eyes and is less likely to make our brains think it’s still daytime. As you would expect, you can control when and if Night Shift is invoked.
What is Night Shift?
Night Shift doesn’t need a separate app, it is a feature of macOS that uses your Mac’s clock and your geographic location to determine whether it’s day or night where you are. It then uses that information to set the color temperature of your display — colder during the daytime and warmer in the evening.
The idea is that by making colors warmer, it won’t disrupt your body’s circadian rhythm, or the body clock that controls them, to the same degree. Night Shift can be turned on and off manually, or you can set a schedule for specific times.
What does Night Shift do?
Your body clock controls circadian rhythm, which has been shown to be key to a number of health conditions. It controls when you feel tired or how you sleep. Disrupting it can be a factor in both physical and mental health problems. So it’s important to go to sleep and wake up at the same time each day. By making your Mac’s display show warmer colors at night, night shift reduces the chance it will interrupt your sleep.
How to enable macOS Night Shift
- Go to the Apple menu and choose System Preferences.
- Select the Displays pane.
- Click on the Night Shift tab.
- Click on the Schedule menu.
- Choose Sunset to Sunrise to have Night Shift turn on and off automatically when it thinks it’s night time where you are.
How to set your own Night Shift schedule
- In Night Shift preferences, click on the Schedule menu.
- Choose Custom.
- Type a start time and finish time into the boxes.
How to control Night Shift manually
- If Night Shift is off, go to the Night Shift tab in System Preferences>Display and check the box labelled Turn on until tomorrow.
- If Night Shift is on, click on the Schedule menu in the Night shift tab and choose ‘Off.’
- Use the color temperature slider in the same window to control the degree to which colors change when Night Switch is turned on or off.
You can also turn Night Shift on or off manually from Notification Center.
- Click on the Notification Center icon in the top right of your Mac’s screen.
- At the very top of the window, in either Today View or Notifications, is a switch labelled Night Shift. Toggle it to switch the feature on or off.
The easiest method of all — ask Siri
You can ask Siri to turn Night shift on your Apple device on and off.
- Click on the Siri button in the menu bar. If you don’t see it, go to System Preferences then click the Siri pane and make sure “Enable ask Siri’ and ‘Show Siri in menu bar’ are both checked. Alternatively, press fn + spacebar.
- Say “Turn on Night Shift.”
- To switch it off, activate Siri again and say “Turn off Night Shift.”
Night Shift works with external displays if your Mac is connected to one (or more). However, it doesn’t work with projectors or televisions.
Night Shift stuck? Here’s how to fix it
Occasionally, usually when a Mac goes to sleep while it’s on, Night Shift can become stuck in the “on” setting. When this happens, turning it off then on then off again doesn’t seem to have much effect. There is a solution, though.
- Go to System Preferences and choose Displays then click the Night Shift tab.
- With Night Shift on, make sure “Turn on until tomorrow” is unchecked.
- Slide the warmth slider all the way to the left, then all the way to the right again.
That should fix it and you should now be able to switch Night Shift off.
If that doesn’t work, try running macOS maintenance scripts using CleanMyMac X. These maintenance scripts can fix problems with files on your Mac that can cause all sorts of problems. CleanMyMac makes it very easy to run them.

Limitations
Night Shift can be great, particularly when your eyes are tired – the warmer light is much less harsh on them than cold blue light. However, it does make colors look different. So you wouldn’t want to have it on while you’re editing photographs or video. Also, you can’t deactivate it for specific apps or Mission Control desktops — it’s all or nothing. For tasks that involve writing, or working with spreadsheets, however, it’s excellent.
Night Shift is a very useful feature than can make it easier for your eyes to focus on your Mac’s display late in the evening. It also reduces the risk of disrupting your body clock and interfering with your sleep, which can lead to health problems. It’s very easy to use and there are options for how warm the screen becomes when it’s on, as well as for scheduling when it starts and stops.
