macmon

Sudoless performance monitoring CLI tool for Apple Silicon processors.

Motivation

Apple Silicon processors don't provide an easy way to see live power consumption. I was interested in this information while testing local LLM models. asitop is a nice and simple TUI to quickly see current metrics, but it reads data from powermetrics and requires root privileges. macmon uses a private macOS API to gather metrics (essentially the same as powermetrics) but runs without sudo. 🎉

🌟 Features

🚫 Works without sudo
⚡ Real-time CPU / GPU / ANE power usage
📊 CPU utilization per cluster
💾 RAM / Swap usage
📈 Historical charts + avg / max values
🪟 Can be rendered in a small window
🦀 Written in Rust

🍺 Install via Homebrew

brew install vladkens/tap/macmon

📦 Install from source

Install Rust toolchain
