Mavericks+: (Desktop Wallpaper) How can I use both the Apple Desktop Pictures and a local folder? I enjoy the built in wallpapers that are shipped with Mavericks, but I also want to supplant those with the wallpapers that I have within my user folder.

In System Preferences -> Desktop &amp; Screen Saver, the option only appears to be EITHER the Apple -> Desktop Pictures OR Folders -> My local wallpaper folder.

Does anyone know of a way to blend the two and have both sets cycle through?
You can move your wallpapers into /Library/Desktop Pictures/ and have them in single location. This shouldn’t affect the system because I have the wallpapers since Leopard and each OS update only include more wallpapers.

Go ahead and include yours in there. Make sure you make a backup of /Library/Desktop Pictures/ just in case you want to revert them back to default state.
