The new 14-inch and 16-inch MacBook Pro models feature an illuminated Apple logo powered by a custom LED light source. The Backglow utility provides an interface to interact with this hardware feature:
- Brightness Control: Manually override the ambient light sensor-based brightness.
- Breathe Mode: Replicates the classic sleep indicator pulse.
- Music Sync: Visualizes audio output via the LED.
- Agent Integration: Provides visual feedback for background processes like Claude Code.
This utility simplifies tasks that would otherwise require low-level system interaction.
