What is MacBar?
MacBar is a lightweight macOS and Windows menu bar system monitor designed as a privacy-focused alternative to iStat Menus. It displays real-time CPU usage, temperature readings from SMC sensors, network activity, and includes a Mandelbrot-based CPU benchmark. The entire app compiles directly from source on your machine — nothing prebuilt is downloaded. Written in Swift and with 100+ downloads, it is distributed as a single shell script installer. No telemetry, no data collection, no subscriptions.

Finally, a Mac monitor that doesn't spy on you I've tried half a dozen system monitors for macOS and rNitro is the first one that feels like it's actually built for the user, not for collecting data. The CLI has that satisfying btop-style TUI — real-time CPU stats without the bloat, without a background service phoning home, without a subscription paywall.
Setup was a one-liner curl install, checksums included so I could verify what I was running before I ran it. That alone puts it ahead of most "free" utilities in this space.
If you want to actually see what your CPU is doing instead of guessing, this is it.

A thoughtful tool.
rNitro does exactly what it says: it tucks a clean system monitor into your menu bar and stays out of the way. What stands out is the care behind the choices — it's free, open source, no subscriptions.
The design is genuinely nice, too. The icon is sharp and the readout is easy to read at a glance. For a lightweight utility, it hits the right balance: useful information without clutter.
Worth a look if you want a no-nonsense way to keep an eye on your Mac.
i agree plenty very useful software
Excellent effort! Convenient All In One!
