dupeguru
dupeGuru is a duplicate file finder for macOS that helps you locate and manage repeated files, music tracks, and similar pictures.
What is dupeguru?
dupeGuru is a macOS utility for finding duplicate files and reducing clutter in folders, media libraries, and photo collections. It scans by filename or file contents, and it also includes dedicated Music and Picture modes for matching songs by tags and finding similar images. The app is aimed at users who need more control than a simple one-click cleaner, with options to sort, filter, review, and choose which files to keep. dupeGuru can move, copy, or remove duplicates after review, making it useful for drive cleanup, archive organization, and media library maintenance. It is published by Andrew Senetar and is also available on other desktop platforms, but Mac users will typically use it as a native duplicate-finding tool for local storage.

Safety overview
Status: Safe
dupeGuru is a legitimate duplicate-finding utility, and its file access is consistent with its purpose because it needs permission to scan folders you choose and remove duplicates you approve. Its built-in reference folder and group reference features are designed to help prevent accidental deletion of the wrong file. Use normal caution before deleting duplicates, especially on external drives, shared folders, or large media libraries where mistaken removals can be harder to undo.
Recommendation: Keep dupeGuru if you use it to clean up duplicate files, music, or pictures. If you no longer need it, you can remove the app and its support files without affecting macOS, but any cleanup workflows or saved app data tied to dupeGuru will no longer be available.
