Why your Mac sleeps while running Docker
Docker containers run as background processes. macOS doesn't consider container activity as user activity. Long-running containers, builds, and docker-compose operations can be interrupted by sleep.
macOS tracks idle time based on mouse and keyboard input, not CPU or app activity. If you're not actively moving the mouse while Docker does its thing, the idle timer counts down and your Mac sleeps.
Keep your Mac awake with Shake It On
Shake It On moves your mouse slightly at regular intervals, resetting the idle timer. It only runs when your conditions are met, so it activates when Docker is working and stops when you're done.
Best condition for Docker: Only Shake If CPU is above 15%
Quick setup
- Install Shake It On and grant Accessibility permission
- Open Settings from the menu bar icon
- Under "Only Shake If," enable the condition: Only Shake If CPU is above 15%
- Under "Paused When," enable "On battery" to save power when unplugged
- For long overnight operations, enable "Allow display to sleep" in the General section so the screen turns off but the system stays awake
