Wallpaper Weekends is a series that works to bring you stunning, high quality wallpapers for your iPad, iPhone, iPod touch, Mac, and Apple Watch.
Betas of macOS Sierra, 10.12.2 now include four new wallpapers to choose from, including the “Color Burst” wallpapers used in ads and other marketing materials for the recently released new MacBook Pro lineup. The wallpapers include three color variations of the Color Burst wallpapers, along with a fourth wallpaper: “Abstract Shapes”.
Download & Installation Instructions for Mac Wallpaper
From your Mac, click your mouse pointer on one of the images. When the full-sized image appears in your browser, right-click or CTRL-Click on the image, and click on “Save Image As…” to save the image to your Mac’s hard drive.
Now, right-click or CTRL-click on your desktop, and select “ChangeDesktop Background…” In the Desktop & Screen Saver dialog box that appears, click the “+” button at the bottom of the left panel. Navigate to the directory you saved the wallpaper in, and double-click the wallpaper filename.
Or, as reader Biff Bifferson pointed out, you can just right click on the image in the browser and click “Set As Desktop Background.” That both changes the desktop AND saves the image. So many options!
