About:
Macmon provides real-time CPU and GPU power consumption metrics for Apple Silicon chips directly in the terminal. It leverages Apple's System Management Controller (SMC) to deliver accurate hardware-level data without requiring root privileges. This makes it a lightweight, privacy-focused alternative to heavy GUI monitoring suites.
Key Features:
  • Sudoless operation for safe, user-level monitoring
  • Real-time TDP and power usage visualization
  • Apple Silicon native support (M1, M2, M3)
  • Low overhead and terminal-based interface
Use Cases:
  • Monitoring power efficiency during development workflows
  • Benchmarking CPU/GPU workloads without external hardware
  • Debugging background process energy consumption
Alternatives:
  • powermetrics – Native macOS tool requiring root; more verbose output
  • iStat Menus – Paid GUI app with system-wide stats; heavier resource footprint
