Project history

Jean-David Gadina’s Hot project was created as a small macOS menu-bar utility for displaying CPU thermal constraints. It later adapted its interface to Apple Silicon, where the available telemetry differs from Intel Macs, and added sensor graphs, filtering, improved hardware coverage, and macOS compatibility fixes.

Adoption history

Hot is distributed as an open-source macOS application and through Homebrew. Its official repository has attracted a substantial user and contributor audience for a focused menu-bar utility.

How it is used

On Intel Macs, users watch temperature, CPU speed limit, scheduler limit, and available CPUs; the display warns when the speed limit falls below its configured threshold. On Apple Silicon, users monitor temperature and the system thermal-pressure state and can open a graph of available sensors.

Why package nerds care

Hot exposes thermal throttling signals that macOS users otherwise have little reason to inspect until performance falls. It is especially useful to package and performance enthusiasts comparing sustained workloads, cooling behavior, and the different telemetry available on Intel and Apple Silicon Macs.

Timeline

• Intel-era behavior: Hot displays CPU temperature, speed and scheduler limits, and available CPU count.
• Apple Silicon support: Hot shifted to temperature and system thermal-pressure reporting because Intel-style limit values are unavailable.
• Recent releases: Sensor accuracy, filtering, graph presentation, and current-macOS compatibility were improved.

Related projects

• Hot reads macOS hardware and operating-system thermal information; it is not a fan-control utility.
