A user on a macOS system reports that their computer is running extremely slowly, and applications are frequently freezing. They suspect a particular application is consuming excessive system resources. Which macOS utility should the user open to identify which processes are using the most CPU, memory, or disk I/O?
- AConsole
- BDisk Utility
- CActivity Monitor
- DSystem Information
Show answer & explanationAnswer & explanation
Correct answer: C. Activity Monitor
Activity Monitor is the macOS equivalent of Windows Task Manager. It provides real-time information about CPU, memory, energy, disk, and network usage, allowing users to identify and manage resource-intensive processes.
Why the other options are wrong
- A. Console displays system log messages, not real-time resource usage.
- B. Disk Utility manages disk partitions, formats, and repairs, not running processes.
- D. System Information provides detailed hardware and software configuration reports, not real-time process monitoring.
