Do not remove a candidate when you believe its application is still installed or another app uses it.
Reconnect app locations
Mount external disks containing applications. An inaccessible app bundle can make its support data appear abandoned.
Check related apps
Apps from the same developer can share group containers, updaters, templates, and support databases.
Wait for updates
An updater can temporarily replace an app bundle. Finish the update and rescan.
Compare identifiers and paths
Reveal both the installed app and proposed leftover in Finder. Preserve user-created documents and data whose owner remains uncertain.
Report a likely false match
Include the app name, developer, installed path, proposed leftover path, diCleaner version, and macOS version. Redact personal path components if needed.
