A user's Mac is running extremely slowly, and Activity Monitor shows a process named 'kernel_task' using a high percentage of CPU. The user asks you to force quit 'kernel_task' to speed up the Mac. What should you do?

Restart the Mac to reset 'kernel_task' and improve performance.

Explain that 'kernel_task' cannot be force quit and that high CPU usage often indicates thermal throttling; check for overheating and heavy background activity.

Force quit 'kernel_task' in Activity Monitor to reduce CPU usage.

Disable 'kernel_task' by running 'sudo launchctl unload' in Terminal.

A user wants to back up their Mac's Desktop and Documents folders to iCloud so they can access them from another Mac. They have enough iCloud storage. What should you instruct the user to do?

Turn on iCloud Backup in System Settings.

Enable iCloud Drive and turn on 'Desktop & Documents Folders' in System Settings > Apple ID > iCloud.

Use Time Machine to back up to iCloud.

Copy the folders to iCloud Drive manually in Finder.

A user's MacBook Pro battery drains quickly when the lid is closed overnight. The user has already disabled 'Power Nap' and 'Wake for network access'. What else could be causing the drain, and what should you check?

Replace the battery because it is likely degraded.

Check for background processes in Activity Monitor that are preventing sleep, such as 'nsurlsessiond' or 'bird'.

Set the display brightness to a lower level before closing the lid.

Turn off Bluetooth and Wi-Fi before closing the lid.

A user reports that a website they visit daily now shows outdated content and login errors. Other users on the same network see the current version. The user is using Safari on macOS. What should you instruct the user to do first?

Use AirDrop to send the website URL to another device and open it there.

Restart the Mac to clear the browser cache automatically.

In System Settings > Privacy & Security, grant Safari permission to access the network.

Clear Safari's cache and website data for that site, then reload the page.
