mectrics

Mectrics is a free and open-source system monitoring application designed specifically for macOS. It provides users with real-time performance metrics displayed conveniently in the menu bar, offering an at-a-glance overview of their Mac's health and activity. The tool is lightweight and focuses on delivering essential information without cluttering the user interface. Users can customize which metrics are shown in the menu bar, allowing them to prioritize the information most relevant to their needs. Mectrics supports monitoring key system components such as CPU, Memory, Battery, Network, Disk, and GPU. For a more detailed understanding, clicking on any menu bar item reveals a popover with in-depth information, such as per-core CPU usage or live disk throughput. It also features threshold alerts, notifying users when a specific metric goes beyond a set limit. This tool is ideal for macOS users who want to keep a close eye on their system's performance without installing heavy or resource-intensive monitoring software. Its open-source nature and commitment to privacy (nothing leaves your Mac) make it a trustworthy option for those concerned about data security.
