Duplicate Detective is a utility for macOS that scans hard drives to find and remove duplicate files and folders, helping free up storage space and improve system performance. The app uses SHA-1 hash checksum algorithms for accurate duplicate detection across file types including images, documents, music and archives, and supports scanning individual folders, external drives, network volumes, Photos and iPhoto libraries. It offers filtering and sorting by file type, size, name and age, a preview feature for examining duplicates before deletion, and options to move files to Trash or create aliases instead of deleting. The interface is designed to be intuitive with minimal setup required. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionUpdate to the native Apple Silicon build of Duplicate Detective. The community has confirmed a Universal Binary version is running on real Macs, so a native build is available now. Visit the official download page at fiplab.com or re-download from where you originally obtained the app — the current installer should automatically serve the native build on Apple Silicon Macs. If the app was installed via the Mac App Store, open the App Store, find Duplicate Detective, and click Update to fetch the native version. After updating, your existing scan history, preferences and library data will be preserved automatically. You will see noticeably faster scan times and lower CPU usage on M-series Macs compared to running the Intel build under Rosetta.
