In the Activity Monitor window, you can view real-time data about CPU usage, memory usage, disk activity, network usage, and more. You can also sort processes by different criteria and force-quit unresponsive applications.

2. Using System Information

The System Information app provides a comprehensive overview of hardware and software configuration on your Mac. To access it:

  1. Select the Apple menu in the top-left corner of your screen.
  2. “About This Mac”.
  3. In the About This Mac window, click on the “System Report” button.

The System Information app will open with detailed information about your Mac’s hardware components such as processor, memory, storage devices, graphics card, and more. You can explore different categories to gather specific system data for troubleshooting or research purposes.

3. Using Terminal Commands

The Terminal app allows you to access system data using command-line commands. Here are a few commonly used commands:

  • top: Displays real-time information about processes and system usage.
  • df: Shows disk space usage for mounted file systems.

  • sysctl: Retrieves various kernel and system information.

To open Terminal, you can either search for it in Spotlight or find it in the Utilities folder within the Applications folder. Once open, simply type the desired command and press Enter to execute it.

4. Using Third-Party Apps

There are several third-party applications available that offer advanced system monitoring and data analysis features. Some popular options include:

  • iStat Menus: Provides a comprehensive menu bar interface with detailed system stats.
