Dark Mode in macOS Mojave helps you focus on what’s important and lets everything else fade into the background. Turn it on to bring your work front and center, and see your desktop transform with a new dark look.
Turn on Dark Mode
- From the Apple () menu, choose System Preferences.
- Click General.
- From the Appearance options at the top of the window, select Dark.
