Show HN: rNitro – free open-source macOS menu bar system monitor

rNitro is a free, open-source menu bar system monitor for macOS (14+).

It shows live CPU, temperature, battery %, GPU, RAM, and network — local sensors only,
no account, no product telemetry. Optional AI chat uses API keys you store in Keychain.

Install: App ZIP from the site or GitHub Releases. Builds are ad-hoc signed for now
(right-click → Open on first launch if Gatekeeper blocks).
