Apple announced iOS 26 and macOS Tahoe 26 at WWDC yesterday, and they're already available as developer betas on supported iPhones and Macs. Besides the new Liquid Glass design language, Apple also has a brand-new set of wallpapers that complement the design. If you don't have an iPhone or don't want to enrol yours into developer beta, you can download the new iOS 26 and macOS Tahoe 26 wallpapers instead.
Both iOS 26 and macOS Tahoe 26 have two sets of wallpapers each — one for light mode and another for dark. The elements of the wallpapers look glass-like and blend well with the latest Liquid Glass design language. Both wallpapers blend Blue, Green, White, and Dark Blue hues with a touch of translucence to create a glass like effect.

The ones for macOS Tahoe 26 have a flowy structure which feels like the flow of water. The dark mode macOS Tahoe wallpaper adopts a purple hue alongside dark blue, which looks fantastic. It reminds us of Windows Vista's Aero theme which had similar wallpapers going for it.
You can download these high quality, full resolution wallpapers from the Google Drive link above and apply it to your desktop or phone with ease. However, you should get these automatically if you update to iOS 26 or macOS Tahoe 26 via the developer beta.
