  • Linux — x64 (AppImage)
  • Git installed and available in your PATH

Download

Once your account is approved, the Downloads page becomes available. Sign in and visit Downloads. Your platform is auto-detected with the recommended download shown first.

Install

macOS

  1. Open the downloaded .dmg file
  2. Drag Quarterback into your Applications folder
  3. Launch Quarterback from Applications

Note for Mac users: The app is not yet code-signed — we’re actively working on getting an Apple Developer certificate and will have this resolved soon. In the meantime, macOS will block the app from opening. To work around this, run the following command in Terminal after dragging the app to Applications:

xattr -c "/Applications/QB Desktop.app"

Then launch QB Desktop from Applications normally. We apologize for the extra step — this will go away once the app is signed.

Windows

  1. Run the downloaded .exe installer
  2. Launch Quarterback from the Start menu

Windows may show a SmartScreen warning since the app is not code-signed. Click More info then Run anyway to proceed.

Linux

  1. Make the AppImage executable: chmod +x QB-Desktop_*.AppImage
  2. Run it directly: ./QB-Desktop_*.AppImage

Sign In

Once launched, you’ll see the sign-in screen. Click Sign in to authenticate with your existing platform account via a device code flow — the app opens your browser, you confirm the code, and the desktop app is paired.

Next, learn about contexts — create your first workspace and start a conversation.
