Make sure the “Privacy” tab is selected.

Navigate to “System Preferences > Security & Privacy.”.Select the “Apple” logo from your Mac’s menu bar.To ensure your dynamic wallpaper is consistent with sunrise and sunset in your current locale, you’ll need to enable macOS’ location services: If Dynamic Desktop is out of sync, then it’s possible that macOS doesn’t know where you are in the world! Is macOS displaying a brightly-lit sand dune during the evening? Or perhaps it’s switching to twilight images hours before sundown?

Your Mac will now be using Dynamic Desktop, and your wallpaper should update automatically throughout the day.
