This is an early build. Apple has not signed or notarized it — that takes a paid developer certificate we don't have yet — so macOS will stop it the first time you open it and ask you to allow it by hand.
Inside is the same Eggent server that runs Eggent Cloud, wrapped in a Mac app. Open it only if you trust us to have built it. Keep a copy of anything you can't lose, and check that the file you got matches the checksum on the right before you open it.
And the agent runs commands in a terminal as your user, with no box around it like the cloud's. Ask it for things you'd be comfortable with it doing.
