About:
Hot is a lightweight menu bar utility for macOS that monitors and displays the current CPU speed limit imposed by the system's thermal management. It provides real-time visibility into performance throttling caused by overheating, helping users diagnose thermal issues. The tool is especially useful for diagnosing performance drops during intensive tasks like video rendering or gaming.
Key Features:
  • Real-time CPU speed limit monitoring
  • Non-intrusive menu bar icon display
  • Detailed thermal throttling information
  • Lightweight and native macOS application
Use Cases:
