Real-time Apple Silicon system monitor for your menu bar
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
My Mac was running hot and I had no idea why.
I went down the rabbit hole — tried a bunch of open source tools on GitHub, some terminal commands that half-worked, deep cleaning scripts that did something but I could never tell what. Eventually I caved and tried iStatMenus. It was great, but I didn't want to pay a subscription just to know what my own computer is doing.
What I actually wanted was simple: something always visible, that just works, that tells me right now — is my Mac okay? What's eating the CPU? Why is it warm? Is the battery degrading?
Nothing free quite hit that. The terminal stuff was powerful but you had to remember the commands. The open source apps I found were either outdated, required too much setup, or crashed on Apple Silicon.
So I built MacMonitor. Starts in your menu bar. Updates every 2 seconds. One click opens the full picture — every core, GPU, temps, battery health, power draw, what process is responsible. No subscription, no account, no nonsense.
Install in one line:
brew tap ryyansafar/macmonitor && brew install --cask macmonitor
Fully open source on GitHub. If your Mac is running hot and you're not sure why — this is for you.
