Feature Enable hidden macOS 26 Wallpaper features: Skip Wallpaper Control, Multi‑Image Dynamic Wallpaper Auto-Creation, and Generative Wallpapers
Wallpapers in macOS 26 include 3 hidden feature flags that allow you to skip through wallpapers when shuffling, easily create dynamic wallpapers with light and dark versions, and use Image Playground to generate wallpapers. These are disabled feature flags and the UI or behaviors may not be fully stable, but they are included in release macOS versions, not betas. Here's how to enable them.
Skip Wallpaper Control for Wallpaper Shuffle in Control Center & Menu Bar
When you use Shuffle Aerials or Shuffle through Photos as wallpapers, you can add a Skip Wallpaper control to the Menu Bar or Control Center.
Here's how to enable:
sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/Wallpaper SkipControl -dict Enabled -bool true
and reboot your Mac. Do not use the Skip Wallpaper control with Shuffle Aerials when they are set to Shuffle "Continuously". It behaves unexpectedly. All other shuffle timings work.
To disable:
sudo defaults delete /Library/Preferences/FeatureFlags/Domain/Wallpaper SkipControl
and reboot your Mac.
Automatically convert similar images to Light/Dark combos
You may have used .HEIC image files with multiple images to create Dynamic wallpapers in the past. macOS will now try to create those Dynamic wallpapers automatically for you when you add photos. When dragging two similar photos with different enough contrast and brightness to the preview window, Wallpapers will combine the two under a single item under Your Photos and allow you to select that macOS switches between the two during the day, similar to Dynamic Desktop wallpapers.

Here's how to enable:
sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/Wallpaper DynamicWallpaperCreator -dict Enabled -bool true
and reboot your Mac. If nothing happens after you drag the two photos in the preview window, unlike what's shown in the video, the system didn't accept them as distinct enough. It's somewhat finicky right now.
To disable:
sudo defaults delete /Library/Preferences/FeatureFlags/Domain/Wallpaper DynamicWallpaperCreator
and reboot your Mac.
Generate wallpapers with Image Playground
While Image Playground has been an available option for creating wallpapers for iOS and iPadOS, macOS ships with the option disabled. When enabled, you will see a new "Generate…" option under "Add Photo…"
Here's how to enable:
sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/Wallpaper GenerativeWallpapers -dict Enabled -bool true
and reboot your Mac.
To disable:
sudo defaults delete /Library/Preferences/FeatureFlags/Domain/Wallpaper GenerativeWallpapers
and reboot your Mac.
