Troubleshooting
Window is not visible
From the macOS top bar select File → New → New Window. You can also click the OS Engine status bar icon and choose “Show Window”.
Why this happens: closing the window does not quit the app. OS Engine can run as a menu bar app, hiding the main window while keeping wallpapers active. Reopen a window via File → New Window or the status bar icon.
No wallpaper showing
Ensure a wallpaper is selected and running. If on battery or fullscreen, auto‑pause may be active — interact with the app or exit fullscreen to resume.
High resource usage
Prefer shorter/lower‑resolution clips and enable automation to pause during fullscreen or on battery.
