What is wallpaper.export?

wallpaper.export handles wallpaper rendering in recent macOS versions.

What is wallpaper.export?

wallpaper.export renders and prepares wallpaper images for the system. Starting with macOS Sonoma, Apple added moving wallpapers (including slow-motion video and interactive wallpapers) that need rendering before they can appear on the desktop and lock screen.

What does it do?

The process handles:

• Rendering wallpaper previews for the picker in System Settings
• Preparing frames from video and moving wallpapers
• Building wallpaper images for the lock screen
• Processing wallpaper shuffle settings

When does it run?

wallpaper.export runs when:

• You browse wallpapers in System Settings
• A moving or video wallpaper needs rendering
• The lock screen wallpaper is being built
• Wallpaper shuffle switches to a new image

Does it use many resources?

Briefly, while rendering. Video and moving wallpapers need more processing than still images. Once the wallpaper is rendered and saved, it uses very little.

Should you worry?

No. It is a normal macOS process for the wallpaper system.
