MacMonitor is a free, open-source system monitor built specifically for Apple Silicon (M1–M4). It lives in your menu bar, updates every 2 seconds, and opens a full dark-mode dashboard showing CPU per-core usage, GPU, memory, battery health, power rails, network, disk I/O, and your top processes — all from the metal, no subscriptions. Install in one command: brew tap ryyansafar/macmonitor && brew install --cask macmonitor
