Every year (at least for the past several), Rocket Yard has posted the wallpaper images for macOS and iOS ahead of their official launch dates. And this year, macOS Catalina and iOS 13 are no different!
iOS 13 comes with eight stock wallpaper images in light and dark versions of blue, orange, green and gray. Catalina offers stunningly beautiful Light Mode and Dark Mode wallpapers.
Clicking on an image will open its full-sized, high-resolution version in a separate window.
