  1. 1

    Install

    Open the downloaded .dmg and drag Plumb into your Applications folder.

  2. 2

    First launch: right-click → Open

    The very first time, right-click (or Control-click) Plumb and choose “Open”, then “Open” again. Plumb is a beta that isn't Apple-notarized yet, so macOS asks once. After this it opens normally with a double-click.

  3. 3

    Allow audio recording

    On your first recording, macOS prompts for the Screen & System Audio Recording permission. It’s required to capture the other side of a call — grant it and you’re set.

Summaries are optional and use your own Claude, ChatGPT, or Gemini API key — Plumb doesn't bundle AI credits. Recording and local transcription need no key.

Is the right-click step safe?

Yes. The extra click exists only because Plumb is a beta that isn't Apple-notarized yet — there's no paid Apple Developer account on it so far. The auto-updater still verifies a SHA-256 hash and an ed25519 signature on every update before swapping the app in place, so you always know you're getting the real build. After an update, macOS may ask you to re-enter your keychain password once; that goes away with notarization.
