Full Disk Access is not detected

Enable the active copy

Open System Settings → Privacy & Security → Full Disk Access and enable the diCleaner copy stored in Applications.

Restart the app

Quit diCleaner completely and reopen it. Start a new scan; old results remain partial.

Remove duplicate entries

macOS can list an App Store build, direct build, beta, or relocated copy separately. Disable obsolete entries and keep the one you actually open.

Refresh the state

Turn access off, quit diCleaner, restart the Mac, and enable it again. Then open diCleaner from Applications.

Understand limits

Full Disk Access does not replace selected-folder access, administrator authorization, or a mounted and healthy disk. A specific path can remain unavailable for another reason.
