# Why does the duplicate scan say "Waiting" and never seem to run?

It's waiting on purpose, and the status line tells you what for. Background scanning holds off so it never interrupts you:

- *"Waiting until you step away for a moment"* — you're actively using your Mac.
- *"Waiting until you're on power"* — This Mac is only scanned while plugged in.
- *"Waiting — Low Power Mode is on"*.
- *"Waiting — your Mac is running hot"*.
- *"Auto-scan: next check in about …"* — it ran recently and will check again later.

If you don't want to wait, click **Scan now** to check that source straight away.
