220-1202 Practice Question: That their MacBook Pro running macOS Monterey…
A user reports that their MacBook Pro running macOS Monterey frequently displays a message saying 'Your system has run out of application memory.' They have 16 GB of RAM and are only using Safari and Mail. Which macOS tool should you use to investigate the cause?
⚠ Common exam trap
The A+ exam often tests the distinction between diagnostic tools by making candidates confuse a static information tool (System Information) or a log viewer (Console) with a real-time performance monitor (Activity Monitor), especially when the symptom is a dynamic resource exhaustion issue.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Activity Monitor
Activity Monitor is the correct tool because it provides real-time, graphical monitoring of memory pressure, process-specific memory usage, and the 'Memory' tab's 'Memory Pressure' graph directly indicates whether the system is under memory strain. Since the user has 16 GB of RAM and is only using Safari and Mail, the 'out of application memory' error typically indicates a memory leak or excessive memory consumption by a specific process, which Activity Monitor can pinpoint by sorting processes by memory usage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
System Information
Why it's wrong here
System Information (formerly System Profiler) aggregates static hardware and software configuration data, including the total installed RAM capacity and its specifications. While it confirms the physical memory present in the system, it fundamentally lacks dynamic metrics such as current memory utilization, active application memory footprints, or the critical "memory pressure" indicator. Consequently, it is not designed for real-time troubleshooting of performance bottlenecks caused by insufficient RAM or memory leaks.
- ✗
Terminal with 'vm_stat' command
Why it's wrong here
The `vm_stat` command in Terminal provides highly granular, raw virtual memory statistics, detailing page ins/outs, page faults, and the distribution of memory pages (free, active, inactive, wired). While invaluable for advanced system debugging and understanding low-level kernel memory operations, interpreting these command-line statistics requires a deep understanding of macOS memory management. For a technician needing a quick, visual overview of memory pressure and per-process consumption, Activity Monitor offers a more intuitive and efficient graphical interface.
- ✓
Activity Monitor
Why this is correct
Activity Monitor is the definitive graphical utility for real-time system resource monitoring on macOS, and its Memory tab is specifically engineered for diagnosing memory-related performance issues. It prominently displays a "Memory Pressure" graph, which visually indicates how efficiently the system is utilizing its RAM, alongside a detailed breakdown of memory usage per process, including "Compressed Memory" and "Swap Used." This comprehensive, user-friendly view empowers technicians to swiftly identify memory-intensive applications, memory leaks, or system-wide memory contention.
- ✗
Console
Why it's wrong here
Console is primarily a log viewer application that aggregates system logs, diagnostic reports, and crash data from macOS and various applications. While it can display historical entries related to memory errors, application crashes, or kernel panics that have already occurred, it does not provide dynamic, real-time metrics of current memory usage, memory pressure, or per-process memory consumption. Therefore, Console serves as a post-mortem analysis tool for memory-related incidents rather than a live diagnostic utility for active memory performance.
