macOS Ventura adds the ability to implement automatically rotating wallpaper images. You can choose a folder full of photos or an album in the Photos app, and have your Mac automatically cycle through those photos. Here’s how:
° Save the wallpapers you want to use in a folder or in the Photos app.
° Click on the Finder and open System Settings.
° Scroll to the bottom of the Wallpaper pane.
° Click on the Add Folder button.
° A new pop-up window will appear. Choose the folder containing the images you want to set as the wallpaper.
° Click on the Choose button. You should see the folder in the Wallpaper Settings panel now.
° Click on the Auto-Rotate button to start using auto-changing wallpapers.
° At the top of the Wallpaper pane, you’ll see a timer next to the Change Picture option.
° Select the time interval you want between the current and the next wallpaper.
° Check the box next to the “Randomly” option and choose how you want the wallpaper to fit on your Mac’s screen.
To remove a folder album from Wallpaper, go to System Settings. Click on the “x” button while you hover the cursor next to the folder name.
