Hot on the heels of Apple’s big batch of beta software released this morning, the company has also seeded the third beta of macOS Mojave to developers.

macOS Mojave brings a number of UI changes to the Mac, including a new Dark Mode and Dynamic Wallpapers. It also comes with a new way to install updates.

Dynamic wallpapers are about to change the look of your Mac once Mojave launches to the public, but you don’t have to wait until this fall to get that new new right now.

Mojave includes 16 variations of the same majestic sand dune Apple showed off at WWDC 2018. If you can’t install Mojave on your Mac, you can download the Mojave dynamic wallpapers below.
