Enable live Lock Screen and Screen Saver motion

Live Lock Screen and Screen Saver playback is a Pro feature and requires macOS 26 (Tahoe) or later. Below that version, macOS does not expose the wallpaper APIs that let a third-party app supply Lock Screen video, so MacWall keeps desktop-only playback.

Turn it on

1. Activate Pro — see License and activation.
2. Open MacWall → Settings → Lock Screen.
3. Enable Live Lock Screen & Screen Saver.
4. Pick the wallpaper you want on the Lock Screen. It can be the same loop as your desktop or a different one.
5. Lock your Mac (Control-Command-Q) to confirm the motion applies.

How macOS handles it

• •macOS treats the Lock Screen video as a system wallpaper asset, so the loop is registered with the system rather than drawn by MacWall in real time.
• •The Screen Saver and Lock Screen share the same asset — which is why enabling one shows motion in both.
• •Applying a Lock Screen wallpaper takes a moment the first time: macOS re-encodes and indexes the asset before it appears.

If motion does not appear

1. Confirm you are on a supported macOS version — System Settings → General → About.
2. Confirm Pro is active in MacWall → Settings.
3. Re-apply the wallpaper. If macOS cached a stale asset, re-applying replaces it.
4. Check System Settings → Screen Saver: if another screen saver was selected after MacWall applied its asset, macOS uses that instead.
5. Log out and back in. This is the reliable way to force macOS to reload wallpaper assets.

Still nothing? Send your macOS version and MacWall version to support@macwall.app — behaviour here changes between macOS betas and we track it per build in the changelog.
