What does the Duplicate file finder row in Settings → Services tell me?
Short answer: It shows the background duplicate search: Scanning now, a count of sets you can clean up, Standing by before the first scan, or Off if you've turned background scanning off.
It shows the background search for files that are exact copies of each other:
- Scanning now — a scan is running, only while your Mac is idle and on power.
- Found duplicate sets — it found copies you can safely clean up; open the Duplicates window to review, or let Smart Care handle it.
- Standing by — the first scan hasn't run yet; it will next time your Mac is idle and on power.
- Off (yellow) — you turned background scanning off. You can still scan on demand from the Duplicates window.
