When you use a Dynamic Desktop picture in macOS, the desktop picture automatically changes to match the time of day in your location. Here’s how to enable it:
° Click Wallpaper in System Settings.
° Choose a picture for Dynamic Desktop.
° Choose a Category: Select “Dynamic Wallpapers” or an animated aerial category like “Earth” or “Lake Tahoe.”
° Select the Dynamic Option: Click the thumbnail of the wallpaper you want, then use the dropdown menu (often above the thumbnails) to choose Dynamic, not a static Light or Dark version.
