Download

Installing

1. Unzip the download and drag Nuticast into Applications.
2. Open it. Because it isn't yet notarized through the App Store, macOS Gatekeeper will warn you the first time — right-click the app and choose Open, then confirm in the dialog that appears. You only need to do this once.
3. The app lives in your menu bar. Click its icon to add your first device.
4. The first time it runs, macOS will ask for local network permission — this is required for Bonjour discovery and the proxy relay to work.

Before you install

Make sure Tailscale is already installed and both your Mac and your iPhone are joined to the same tailnet, and that you've enabled Wireless Debugging for the iPhone in Xcode at least once. See the full manual for the exact pairing flow.
