A user calls the help desk saying that after upgrading to macOS Ventura, the 'Documents' folder in the sidebar keeps disappearing after every reboot. They need it to stay visible. Which macOS feature or tool should you use to fix this?
This is exactly where users enable or disable folder visibility in the Finder sidebar.
Why this answer
The correct answer is Finder Preferences because sidebar visibility of folders is controlled there, not in System Settings or via Spotlight. This question tests knowledge of basic macOS UI customization, a common support task.
