Install MoPilot, and what first launch asks for

Take the build for your Mac from the download page — Apple silicon and Intel are separate disk images — and drag MoPilot into Applications. The installer is all there is; nothing downloads on first run.

The build is code-signed with a real Developer ID certificate and notarized, so macOS still shows one download confirmation — click Open. After that it launches like anything else.

First launch is two steps, in this order: sign in, then check it can hear the call. The steps below are the Mac ones — the permissions macOS asks for are its own. There is a Windows build on the same download page, and it is signed too.
