Console is a macOS diagnostic utility used to view log messages, reports, and analytics information generated by the operating system and applications. When an app quits unexpectedly, macOS can generate diagnostic or crash-related information that helps identify what happened around the failure. Apple documents that Console can display analytics information related to events such as applications quitting unexpectedly, forced application termination, and system errors. Therefore, reviewing log data for apps that unexpectedly quit is the correct use described in option D. Console does not dynamically reallocate memory to applications, terminate CPU-intensive background processes automatically, or function primarily as a cache-management utility. Those activities involve other macOS components or tools. Console’s key troubleshooting value is providing diagnostic evidence that can help correlate errors, crashes, and abnormal application behavior.
