Michael HerrmannDisabling dynamic wallpaper video rendering loops, switching to static backgrounds, and clearing Dock expose caches.
Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:
- Switch all desktop spaces to static wallpapers in System Settings > Wallpaper.
- Flush compositor memory:
sudo purge && killall Dock. - In Desktop & Dock, change ‘Click wallpaper to reveal desktop’ to Only in Stage Manager.
Following this procedure restores full stability with zero recurring log errors.
