Stats

Stats is an open-source desktop app that provides a comprehensive system monitor directly in the macOS menu bar. It allows users to track hardware performance and system health in real time, providing a constant stream of data regarding the internal state of the computer without the need to open separate utility windows or activity monitors.

The application is compatible with macOS 12 Monterey and newer versions. Users can install the software manually by downloading a DMG file and moving the application to the folder, or they can use the Homebrew package manager via the terminal for a more automated installation process.

Key features

• Monitoring of CPU and GPU utilization
• Tracking of memory and disk usage
• Network usage monitoring
• Battery level tracking
• Sensor data for temperature, voltage, and power
• Bluetooth device monitoring
• Multiple time zone clock
• Legacy fan control for older Mac models

The software is designed for macOS users who require constant visibility of their system resources. It includes support for desktop widgets, although these must be explicitly enabled in the settings to allow communication with the system process known as chronod. To maintain energy efficiency and reduce the impact on battery life, users can selectively disable specific modules. The developer notes that the sensors and Bluetooth monitors are the most resource intensive components, and disabling them can reduce the CPU usage of the app by up to 50 percent in some cases.

Regarding data accuracy, the sensor module displays thermal zones rather than individual cores, as Apple changes sensor keys with each new SoC. The app also utilizes external APIs to check for software updates and to retrieve the public IP address for the network module. For users with strict privacy requirements, these requests can be blocked using network filtering tools.

Stats serves as a lightweight, community driven utility for monitoring hardware metrics on Apple hardware.
