duplicate-finder-macos
duplicate-finder is a macOS menu bar app that locates and helps remove duplicate files on your Mac without using the terminal. It scans any folder including Downloads, Documents, Desktop, or the entire home directory to find exact duplicates by file content rather than just filename. The app groups matching duplicates so users can keep one copy and view the exact amount of space that will be freed before deletion. Files are moved to the Trash rather than permanently deleted, ensuring no data is lost without user confirmation. All scanning happens locally on the device with no files, filenames, or metadata being uploaded. The app requires macOS 13 Ventura or later and supports both Apple Silicon and Intel hardware. It is distributed under the MIT license.
