Troubleshooting

Check the installation location, macOS security message, app edition, damaged download, and duplicate copies.

Preserve work, narrow the affected tool and location, update the app, and collect useful reproduction details.

Distinguish active scanning from abnormal resource use and reduce the scan scope before reporting a repeatable issue.

Diagnose folder access, unavailable disks, scan thresholds, cloud files, and other causes of incomplete scans.

Reauthorize the correct Home folder and resolve repeated folder pickers in the App Store edition.

Enable the correct application entry, restart diCleaner, remove duplicates, and refresh a stale macOS permission state.

Resolve files in use, permission failures, read-only volumes, protected containers, and stale removal results.

Check edition availability, Full Disk Access, Home authorization, external volumes, and the current Trash state.

Check Mail data availability, folder authorization, account state, cloud downloads, and application activity.

Finish active updates, review permissions, restart, and avoid forcing removal of files still managed by macOS.

Close helpers, rescan protected related files, use vendor uninstallers, and preserve shared application data.

Repair saved folder access, choose the correct app copy, and refresh permissions when scans unexpectedly show nothing.

Check disconnected application volumes, shared developer data, identifiers, recent updates, and false associations.

Check release channels, duplicate app copies, inaccessible locations, version metadata, and official update sources.

Eject mounted disk images, close installer processes, and check the containing volume’s permissions.

Diagnose connectivity, confirmation settings, service errors, and unsupported items in diCleaner online features.

Check access, protected folders, links, cloud placeholders, snapshots, and files changing during analysis.

Review selected locations, minimum size, cloud availability, ignore rules, and the difference between identical and similar files.

Reduce overlapping locations, raise the minimum size, download required cloud files, and avoid slow network storage.

Check minimum size, local availability, supported formats, scan scope, and the subjective nature of visual similarity.

Authorize the actual folder, check custom screenshot destinations, cloud redirection, and files renamed or moved by another app.

Close the owner, approve matching authorization, use macOS Login Items, and avoid changing managed or protected services.

Check whether a file is open, protected, read-only, synchronized, or stored on unavailable media.

Quit duplicate app copies, remove obsolete login entries, and keep one intended edition in Applications.

Check the active edition, duplicate copies, managed preferences, write access, and whether a setting applies only to new scans.

Create a useful, privacy-conscious report with reproducible steps, versions, paths, permissions, and exact errors.

Interpret permission denied, file not found, file in use, read-only volume, insufficient space, and disconnected storage.

Learn why paths, sizes, and selections can change after scanning and why a fresh scan is safer than repeating an old action.

Create safe working space on the correct volume and avoid deleting unknown system data during a low-storage emergency.
