You'll need to wait until the fall for the updates to iOS 12 and MacOS Mojave to hit, but there's no need to wait for the beautiful wallpapers Apple showed off at WWDC. 

With each software update, Apple introduces new wallpapers to spiff up iOS devices and Macs, and this year is no different. iOS 12's new wallpaper is a colorful splash of red, aqua and blue. Mojave gives you the choice of a sand dune landscape under the desert sun, or the pale, blue light of the moon -- because the update to MacOS features a changing desktop wallpaper as part of its new Dark Mode.
