mtop is a lightweight, open-source CPU and memory monitor that lives in your Mac's menu bar, providing instant access to system performance data with an elegant visual design.

This streamlined system monitor transforms complex performance metrics into an accessible, one-click experience. View your CPU usage, core count, and memory consumption directly from the menu bar without opening terminal applications or complex utilities.

The app serves as a modern alternative to traditional command-line tools like htop and top, bringing the same functionality to a beautifully designed graphical interface. Nine gorgeous color schemes let you customize the appearance to match your personal style or system preferences.

Beyond basic monitoring, mtop provides detailed insights into running processes, including CPU usage, memory consumption, and process IDs. The comprehensive process table gives you complete visibility into what's consuming your system resources.

GPU usage tracking adds another layer of system awareness, particularly valuable for users running graphics-intensive applications or monitoring overall system performance during demanding tasks.

At just 295.5KB, the app maintains an incredibly small footprint while delivering professional-grade monitoring capabilities. The open-source nature ensures transparency and community-driven improvements.

Privacy remains paramount with zero data collection. Everything operates locally on your machine without external communications or tracking, making it perfect for users who value both functionality and privacy.

The developer actively maintains the app with regular updates and bug fixes, ensuring compatibility with the latest macOS versions and optimal performance across different Mac configurations.
