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 50% sustained for 5 minutes (long-render-friendly window)
- Paused When on battery
- Allow display to sleep (saves energy during overnight renders)
Tip
Sustained-CPU is the right answer for 3D work. A long Blender render isn't always pegged at 100% — it dips during file I/O and during certain sample passes. The 5-minute window catches that.Shake It On keeps your Mac awake during 3D modeling with smart conditions. $9.99 one-time.
Keep your Mac awake the easy way.
Shake It On lives in your menu bar and uses organic mouse movement to prevent sleep. Set it once and forget it.
