The Duplicate Finder

The Duplicate Finder (from Rocky Sand Studio) does not appear to be actively maintained — there is no evidence of recent updates, a current vendor website, or a native Apple Silicon build in the search results. As Apple is removing Rosetta 2 in macOS 28 (September 2028), Intel-only apps will stop launching entirely on that release, leaving you without a way to manage duplicates. Rather than wait for an update that may never come, consider switching to Gemini 2, a modern actively maintained duplicate-finder that runs natively on Apple Silicon and offers the same broad functionality — it detects duplicates across photos, music, documents, and more, with real-time monitoring and customisable matching options. Gemini 2 is available on the Mac App Store and can import any library or workflow you have built in your current tool. If you prefer a free option with basic features, Disk Drill (which includes a duplicate photo finder in its free tier) also ships natively on Apple Silicon and is actively maintained by a vendor that still publishes updates regularly.
