Sudoless performance monitoring CLI tool for Apple Silicon processors.
Important
This fork adds experimental support for rendering memory bandwidth. I'm pretty sure I chose the correct metrics, but it's possible I did not. (These are no longer exposed through powermetrics so there is no official tool to check against. If you know of one, let me know.)
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. 🎉
