Install
# Using uv (recommended)
uv tool install macos-smi
# Using pip
pip3 install macos-smi
# From source
git clone https://github.com/tianszz/macos-smi.git
cd macos-smi && uv tool install .
Usage
# CPU + RAM only (no sudo required)
macos-smi
# Full stats including GPU utilization and power draw
sudo macos-smi
# Single snapshot and exit (like nvidia-smi default)
sudo macos-smi --no-loop
# Faster refresh
sudo macos-smi --interval 500
Requirements
- macOS on Apple Silicon (M1 / M2 / M3 / M4)
sudoaccess for GPU stats viapowermetrics(CPU + RAM work without sudo)
How it works
GPU utilization and power draw are read from Apple's powermetrics utility (requires root). CPU utilization and RAM are read via psutil (no sudo needed). The display updates at 1 Hz by default using Rich.
