For macOS Mojave 10.14 onward, Apple has introduced Dark Mode, which is a system-level setting working with all the compatible apps, including the third-party ones. It provides a unique visual interface and desktop environment that is easier for you to focus on your work and easier on your eyes. The Dark them is perhaps the most popular new feature for many Mac users, and the sole reason that some of them update to the latest version of the operating system.
You can easily enable Dark mode, or switch between it and Light mode at any time through the system (macOS Mojave 10.14 or higher) settings. Here are specific tutorials:
1. Pull down the Apple menu and select System Preferences.
2. Click the General pane in the System Preferences window.
3. At the very top of the General settings, click the Dark/Light icon next to Appearance.
4. When it is done, close out of System Preferences.
The apps that come with Apple, such as Photo, Calendar, Mail, and Maps all support Dark Mode. If you want complete darkness on your Mac, there is a further step to go through – tone down the desktop. You can actually choose your own custom image for the desktop, but using a Dynamic desktop image or a dark still image still requires macOS Mojave or higher.
To use the dark desktop image:
1. Open System Preferences again, and select Desktop & Screen Saver.
2. Click the Desktop tab, and select Desktop Pictures in the Apple section of the sidebar.
3. Select one of the Dynamic Desktop images and click Dynamic in the drop-down menu.
If you want to desktop to always remain dark, select Dark (still) from the drop-down menu, or select one of the dark versions of Apple screens in the Desktop Pictures section.
Another way to help relieve eyestrain is Night Shift, which adjusts your display’s brightness and white point balance according to the time to reduce your fatigue. To turn it on, launch System Preferences > Display > Night Shift, as shown below.
