A user connects a USB flash drive to their Mac and copies important files to it. When they try to eject it, macOS says the drive is in use. What should you instruct the user to do?

Close any Finder windows or applications that are accessing files on the drive, then eject again.

Unplug the drive immediately to avoid data loss.

Force eject the drive by holding the Option key and clicking the eject icon.

Restart the Mac to release the drive automatically.

A user connects an external SSD to their Mac to use as a Time Machine backup destination. The drive appears in Finder but Time Machine does not list it as an available backup disk. The drive is formatted as NTFS. What should you do to make the drive usable for Time Machine?

Reformat the drive as APFS or Mac OS Extended (Journaled) using Disk Utility, then select it in Time Machine settings.

In System Settings > Privacy & Security, grant Time Machine full disk access.

Enable 'Show Backup Disks' in Time Machine settings.

Mount the drive manually using the 'mount -t ntfs' command in Terminal.

A user installed a new browser extension in Safari. After the installation, Safari crashes when visiting certain websites. The user wants to keep the extension but needs Safari to work. What should you instruct the user to do?

Use AirDrop to send the extension to another device and test it there.

Clear Safari's cache and website data to remove the corrupted files.

Disable the extension in Safari's Settings > Extensions, then test Safari; if it works, re-enable the extension and update it if available.

In System Settings > Privacy & Security, grant Safari permission to run extensions.

A user reports that a newly installed video-editing app cannot access the camera and microphone, even though the app works otherwise. The user is in a hurry and asks you to fix it quickly. What should you do?

Grant the app Camera and Microphone permissions in System Settings > Privacy & Security.

Use Activity Monitor to force quit the app and relaunch it.

Reinstall the application to reset its permission prompts.

Run the app from the Applications folder instead of from a downloaded disk image.
