For Windows users, the term “Task Manager” is synonymous with managing running applications and system performance. Mac users, on the other hand, have a similar tool called Activity Monitor. Though often overlooked, Activity Monitor plays a crucial role in diagnosing problems, closing unresponsive apps, and monitoring system health. This guide explains how to open Task Manager on a Mac and how to use Activity Monitor effectively.
What is Activity Monitor?
Activity Monitor is macOS’s built-in system monitoring tool. It provides real-time data about your Mac’s CPU, memory, energy, disk, and network usage. In short, it’s macOS’s answer to Windows Task Manager.
With Activity Monitor, users can:
- View running processes and applications
- Check system resource usage
- Force quit unresponsive applications
- Diagnose slow performance or hardware issues
