For example, in the afternoon, the lighting in the wallpaper is at its peak brightness and the image of the Mojave desert is depicted as it would be if you visited it in the daytime with well-lit sand dunes and a bright blue sky.
At night, the sky in the wallpaper shifts to darker blue to reflect that it’s now evening. The shift between daytime and nighttime happens gradually over the course of the day, so you’ll see subtle changes each time you look at your Mac’s display.
Dynamic Desktop is simple to enable. Here’s how:
- Open up System Preferences.
- Choose Desktop & Screensaver.
- Select one of the options from the “Dynamic Desktop” section under “Desktop.”
- Using the dropdown menu underneath the wallpaper’s name, make sure “Dynamic” is enabled.
At the current time, there are two wallpaper options in the macOS Mojave beta, which work with both Light and Dark Mode.
You can choose between the wallpaper that depicts the Mojave desert and a Solar Gradients wallpaper that shifts from a lighter sky blue in the daytime to a darker twilight blue. Apple is likely to add additional Dynamic Desktop options in the future.
Apple’s Dynamic Desktop feature relies on your location to be able to match the lighting of the wallpaper with the lighting outside, so to use it, you will need to have Location Services enabled.
