Download the Mac disk image

One .dmg carries the product folder and installer. The public download URL always serves the current monorepo release — redeploy refreshes it automatically.

Install promise

Private. Safe. Secure.

A product install — not a telemetry funnel. Same posture as the Family Office stack.

Private

Your hardware

Marketing is a brochure. Vault, chat, and models stay on hardware you own. No cloud account. No phone-home.

Safe

Host-only seed

Only The Briefcase.app + suite.manifest. No silent twins, no junk in Applications, no surprise Suite dumps.

Secure

Closed defaults

Loopback organs, optional WireGuard mesh, explicit Suite Get. You publish doors — we don’t.

Three clean ways — pick one

Path B

Installer package (.pkg)

Double-click the standalone .pkg. Installs to /Applications/The Briefcase App and mirrors to ~/Applications. Postinstall prunes junk — host only.

Best for scripted / fleet installs

Download .pkg
Path C · operators

Framework install GUI

On the DMG: Install The Briefcase (GUI).command — FO LED steps. Repo operators: make briefcase-install-gui.

Same DNA as Father console boot

Package details

After install

Open once. Grow only what you need.

1

Launch the host

Open The Briefcase.app from Applications. First launch may need right-click → Open if Gatekeeper asks (unsigned/local builds).

2

Bring the door up

Ensure your organ/door stack is running (family mesh or local). The host talks to doors you control — not a mandatory SaaS.

3

Suite Get (optional)

Settings → Suite apps → Get for Pockit, Voice, Flipper, … Nothing else appears until you ask.

Package files

Version tracks the monorepo release. Prefer the .dmg for a guided, visual install.

Verify integrity (optional)

After download, checksums ship as SHA256SUMS.txt next to the packages on the download host. 

curl -fsSL https://thebriefcase.app/downloads/SHA256SUMS.txt
shasum -a 256 -c <<< "$(grep '\.dmg$' SHA256SUMS.txt)"

Web App

Same door. Any browser.

Family mesh / operator

Default door: http://briefcase.localhost/. Universal App host and Web App share chrome after hard-reload.
