The problem
Your Mac dims or sleeps during a long screen recording, ruining the footage. Especially problematic when recording tutorials or time-lapses.
Why it happens
Screen recording apps like QuickTime or ScreenFlow may not prevent display sleep, especially for very long recordings where you're not interacting with the computer.
The fix: Shake It On
Shake It On keeps your Mac awake by moving the mouse slightly at regular intervals. macOS sees real user activity and resets the idle timer. Set it up with the right conditions and it only runs when you're actually screen recording.
Recommended conditions for screen recording:
- Only Shake If a specific app is running (ScreenFlow, QuickTime)
- Scheduled to recording sessions
