Pidgeon ships five macOS desktop apps: Post, Flock, Loft, Migrate, and the Pidgeon launcher. Each is a separate download. Install only what you need. Current beta release: 0.2.0-beta.1.

​
Requirements

  • macOS 12 (Monterey) or later
  • AI features (optional) run on-device and recommend 16 GB RAM; everything else runs comfortably below that

​
Download and install

1

Download from the catalog

Get the apps from the downloads catalog at downloads.pidgeon.health. The catalog lists every app, its current version, and a SHA-256 checksum per file.
2

Verify the checksum (optional but recommended)

Compare the output against the checksum shown in the catalog. If they differ, do not install: re-download, and contact [email protected] if it still differs.
3

Install

Open the .dmg and drag the app into Applications.

First launch

The macOS apps are signed with an Apple Developer ID certificate (Pattern Engine LLC) and notarized by Apple, so Gatekeeper opens them normally — you won’t see the “cannot be opened because Apple cannot verify it” block. On the very first launch macOS may show a one-time “downloaded from the internet” confirmation; click Open.To confirm the signature and notarization yourself:

Sign in (where needed)

Each app starts its local Bridge sidecar (the engine process) on a loopback port: Loft on localhost:5100, Post on localhost:5101, Flock on localhost:5102. The Bridge binds to loopback only; nothing listens on your network.Post works without an account. Flock, Loft, Migrate, and the launcher ask you to sign in with your Pidgeon account.
