When it was released Mountain Lion, Apple had hidden a bunch of fantastic wallpapers which was only used for screensavers. With Mavericks, did wallpapers disappear from the mainstream, or did you discover them? In the Mountain Lion the photos were on the way:
/System/Library/Frameworks/Screen saver.Framework/Versions/A/Resources/Default Collections/
Like the previous time, these are the photos that Apple uses as screensavers, are very high-resolution photos. To access the folder, tap Command + Shift + G from your computer and it will display the "go to folder" type there, or just copy - paste:
/Library/Screen Savers/Default Collections/
The route will take you to the new position of the screensavers. You can copy and use them as wallpapers.
