The fastest way to get a bug fixed

Open the menu bar icon → Send Feedback…. The window pre-fills with what happened, lets you attach the last 64 KB of diagnostics, and shows exactly what will be sent before you send it. Those diagnostics are what make a fix possible without a back-and-forth.

If you would rather use email, include: what you did, what you expected, what happened, your macOS version, and whether the microphone was the built-in one or a headset.

Common questions

Dictation types nothing. Grant Accessibility in Settings → Permissions, then press the trigger again. If the row stays off, use Reset & Ask Again.

It hears nothing on a Bluetooth headset. The first press can land while the headset is switching profiles; press again. Settings shows which microphone is live.

My licence key does not work. Paste the whole line, including the INMOST1. prefix. Keys are checked on your Mac, so nothing needs to be online.
