Run diCleaner from your own macOS account and review only data you are authorized to manage.
Home folders, Trash, recent items, Mail, Photos, and application data can differ by user. A result from one account does not represent every user.
Do not use administrator authorization to remove another person’s files without permission. Coordinate system-wide application removal and startup changes with all affected users.
Keep personal vault credentials private and lock a vault before switching users.
For an organization-owned Mac, follow administrator and retention policy. Device management can enforce applications, settings, and login items that should not be changed locally.
