The problem
Baking textures, simulating physics, and rendering scenes in Blender, Cinema 4D, or Maya can take hours. Your Mac sleeping mid-bake means starting the whole process over.
Why it happens
3D apps use heavy CPU and GPU but don't always tell macOS to stay awake during automated processes like bakes and simulations.
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 3D modeling.
Recommended conditions for 3D modeling:
- Only Shake If CPU is above 20%
- Paused When on battery
- Allow display to sleep (saves energy during overnight renders)
