About:
DarkModeBuddy leverages the Mac's ambient light sensor to automatically switch between light and dark system appearances. It runs quietly in the background, eliminating the need for manual toggling or time-based schedules. This provides a seamless visual experience that adapts to your physical environment in real-time.
Key Features:
  • Automatic light/dark mode switching based on ambient light
  • Runs as a lightweight background menu bar utility
  • Utilizes built-in Mac hardware sensors
  • No manual configuration or scheduling required
Use Cases:
  • Users working in environments with changing lighting conditions throughout the day
  • Preventing eye strain from overly bright/dark interfaces in variable ambient light
  • Automating system appearance changes without time-based rules
Alternatives:
  • Night Shift – Built-in macOS feature that adjusts color temperature but does not switch system appearance
  • f.lux – Focuses on color temperature adjustment rather than full light/dark mode switching
