INSTALL · PORTABLE DO

Take DO with you.

Download Chrome DO for the browser toolbar, or Mac DO source to build the floating companion on your Mac. Drafts only — nothing is sent or paid for you.

Chrome DO

  1. Click Download Chrome DO — you get assembl-do-extension-1.5.2.zip.
  2. Unzip the folder (keep manifest.json at the top).
  3. Open chrome://extensions → enable Developer mode.
  4. Load unpacked → select the unzipped folder → Reload if it was already installed.
  5. Pin DO. Select page text to light the toolbar badge.

If Chrome marks the extension Inactive, open Errors. Every shipped .js file must start with quoted 'use strict'; — a bare use strict disables the extension. Toolbar icons (16/32/48) are included so Chrome can show the D-mark.

Mac DO

There is no notarised public .app download yet. The button downloads the companion source from apps/do/macos so you can build locally.

  1. Click Download Mac DO → unzip on a Mac with Xcode Command Line Tools.
  2. Run ./build.sh ~/Desktop/do-mac-build then open DO.app.
  3. Optional: bash package.sh ~/Desktop/do-mac-build for a development DMG (still ad-hoc signed).

Gatekeeper may warn on unsigned development builds. Do not disable macOS security protections. A public Mac installer needs Developer ID signing and Apple notarisation — not claimed here.
