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. 🎉
