If you aren't a developer registered for the beta program you won't be able to run Monterey on your Mac, or iOS 15 on your iPhone yet, but you can still get the new wallpapers and pretend you are!
Get in the mood for macOS Monterey by installing the official wallpaper on your desktop. Download Monterey wallpaper.
If it's the iOS 15 wallpaper you are after, we have the link for that too. Normally, several wallpapers come to the iPhone with a new iOS, but so far Apple is only providing two pictures: one for dark mode and one for normal bright mode. Download iOS 15 wallpapers.
The iPhone images are high-resolution, so they can also be used as wallpaper on the iPad or Mac too.
Thanks to our Macwelt colleagues for sharing!
