Go Install Package

Install tasks are managed by the go/install package. You can interact with this package via the command line client, for example, by specifying components to install.

Install the service (in launchd):

keybase install --components=service

Install the helper tool, Fuse and the mount directory, and start KBFS service:

keybase install --components=helper,fuse,mountdir,kbfs

If the installed component requires a privileged task or native code (like Fuse), the go package will call into the native KeybaseInstaller.app (see below).

keybase install-auto

When the Electron app starts up it runs keybase install-auto in shared/desktop/app/installer.js.

By default this runs install with the components:

  • cli: Command line (to /usr/local/bin)
  • updater: Updater in launchd
  • service: Service in launchd
  • kbfs: KBFS in launchd (without mount), needed by chat
  • kbnm: Browser native messaging

If Fuse has been installed (via the Folder tab), it will also install/update the following components:

  • helper: Helper tool which runs privileged tasks
  • fuse: Fuse kext
  • mountdir: Creates /keybase
  • kbfs: KBFS in launchd (with mount)

KeybaseInstaller.app

The KeybaseInstaller.app has options to install native components (via privileged tasks in the Helper tool) via the command line parameters:

For example, to install (or update) Fuse, you can run:

/Applications/Keybase.app/Contents/Resources/KeybaseInstaller.app/Contents/MacOS/Keybase \
  --app-path=/Applications/Keybase.app --run-mode=prod --timeout=60 --install-fuse

Other arguments include:

  • install-fuse: Installs KBFuse, our custom osxfuse build, see Fuse/kbfuse for more details.
  • install-mountdir: Creates the /keybase folder.
  • install-helper: Installs helper tool, which runs privileged tasks. See Privileged Helper Tool.
  • install-cli: Installs command line into /usr/local/bin or /etc/paths.d/Keybase
  • install-app-bundle: Installs app by verifying app bundle and then moving it into /Applications/Keybase.app (as privileged task).

It also has corresponding uninstall options:

  • uninstall-fuse
  • uninstall-mountdir
  • uninstall-helper
  • uninstall-cli
  • uninstall-app
