Mectrics
Mectrics is a macOS menu bar system monitor that shows live CPU, memory, battery, network, disk, GPU, temperature, and fan readings.
What is Mectrics?
Mectrics is a native macOS system monitor designed to keep key Mac hardware and performance readings visible from the menu bar. It helps users watch CPU, memory, battery, network, disk, GPU, temperature, and fan activity without opening a full dashboard or utility window. You can choose which readings stay in the menu bar, open popovers for more detail, and use a compact health view that stays quiet until something needs attention. The app also supports alert rules for sustained conditions, local diagnostics, Notification Center widgets, and a read-only command-line tool for scripts or headless Mac workflows. Mectrics is published by Faruk KAMÇICI and is intended for users who want lightweight, on-device monitoring during everyday work, troubleshooting, or performance tracking on macOS.

Safety overview
Status: Safe
Mectrics is a local system-monitoring app for macOS, so access to hardware and performance information is normal for its purpose. Its monitoring features are read-only, and the app states that telemetry and analytics are not sent from the Mac. It can optionally install a command-line link and support launch-at-login behavior, which are ordinary choices for a menu bar utility. Keep it updated, and only enable background behavior or command-line access if those features fit how you use your Mac.
Recommendation: Keep Mectrics if you use it to watch system health, performance, or alerts from the menu bar. If you no longer monitor your Mac this way, you can remove it without affecting macOS itself, though you will lose its saved layout, rules, widgets, and command-line helper.
