Question 1

Which macOS tool lets you view all running processes and their CPU/memory usage in a graphical interface?

Accepted Answer

Activity Monitor

Answer

Activity Monitor displays all running processes, their CPU, memory, energy, disk, and network usage in a graphical window, making it the primary tool for monitoring and managing processes on macOS.

Question 2

What is the purpose of the macOS Launch Services database?

Accepted Answer

It maps file types and URL schemes to the applications that open them

Answer

The Launch Services database maps file types (UTIs) and URL schemes to registered applications, determining which app opens a given file or URL by default.

Question 3

A user's application consistently crashes at launch after a macOS update. Which folder should you check first for potentially corrupt preference files?

Accepted Answer

~/Library/Preferences/

Answer

Application preference files (.plist) stored in ~/Library/Preferences/ can become corrupt after system updates, causing app crashes. Removing or renaming the app's .plist file forces it to regenerate fresh preferences.

Question 4

Which command-line tool can be used to unload a LaunchAgent or LaunchDaemon without restarting macOS?

Accepted Answer

launchctl

Answer

launchctl is the command-line interface to launchd, macOS's init and service management daemon. It can load, unload, start, stop, and query the status of LaunchAgents and LaunchDaemons.

Question 5

What does the macOS Gatekeeper feature check when a user opens a downloaded application?

Accepted Answer

Whether the app is signed with a valid Apple developer certificate and notarized

Answer

Gatekeeper verifies that downloaded applications are code-signed with a valid Apple Developer ID certificate and, for macOS 10.15+, have been notarized by Apple's automated security scanner.
