Silent install of Symphony (MacOS)

A silent install is an installation of a software program that requires no user interaction. It is a convenient way to streamline the installation process of a desktop application without requiring any user input.

The Symphony Desktop Application (SDA) supports silent installation on MacOS using the standard installer command from the terminal.

2 files are needed to configure the required settings: 

  • A user settings file should be created as "/tmp/sym_settings.txt"
  • A permissions settings file should be created as "/tmp/sym_permissions.txt"

Both files are plain text files containing the values of the corresponding settings. The files are read by a post-install script in the installer.

To avoid installation issues, the user must create both files using the /tmp path exactly as outlined in the instructions below.


  • Depending on your system policies, the user may need to request permission to run the commands.
  • The parameters that must be configured in both files are listed below. They must be configured in this order, as this is the order in which the installer reads them.
  • Do not skip any parameters.

User Settings File

  1. Pod Url:
    POD_URL (String): The web address of the pod that the SDA should connect to (for example,
  2. Minimize On Close:
    MINIMIZE_ON_CLOSE (Boolean): Minimize the SDA (instead of quitting it) when the Close button is selected.
  3. Launch On Startup:
    AUTO_LAUNCH (Boolean): Launch the SDA when the operating system is started.
  4. Always On Top:
    ALWAYS_ON_TOP (Boolean): Force the set SDA window to always stay on top of all other applications' windows.
  5. Bring To Front:
    BRING_TO_FRONT (Boolean): Bring the SDA to the front upon receiving notifications. On Windows, the SDA icon will also flash in the taskbar.
  6. Dev Tools Enabled:
    DEV_TOOLS_ENABLED (Boolean): If true, enables Google Developer Tools for debugging and troubleshooting.

Sample sym_settings.txt file: 
  • companyabc is the name of your Symphony instance.

Permissions Settings File

  1. Media:
    MEDIA (Boolean): If true, allows the SDA to access the camera, audio and microphone, which are necessary for a complete Symphony Meetings experience.
  2. GeoLocation:
    LOCATION (Boolean): If true, allows Symphony to access the user’s location.
    • This feature is not yet available in Symphony, so it can be turned off.
  3. Notifications:
    NOTIFICATIONS: If true, enables Chrome's native notifications. This is required on MacOS where SDA uses HTML notifications, not custom notifications as in Windows.
  4. Midi Sysex:
    MIDI_SYSEX (Boolean): If true, lets Symphony access external connected devices to play MIDI (musical instrument digital information) files.
  5. Pointer Lock:
    POINTER_LOCK (Boolean): If true, locks a pointer within Symphony, which provides input methods based on the relative movement of the mouse cursor over time (for example deltas) - not just the absolute position of the mouse cursor in the viewport.
  6. Full Screen:
    FULL_SCREEN (Boolean): If true, allows the SDA to switch to full screen mode. Full screen is a feature used in Symphony Meetings, so it should be turned on to improve the user experience.
  7. Open External App:
    OPEN_EXTERNAL (Boolean): If true, it enables opening external applications from inside Symphony. This feature must be set to true for users to open browser windows when URLs are selected inside the SDA.

Sample sym_permissions.txt file:


To install the package, use the command below making appropriate changes to the path where the app gets installed:

sudo installer -store -pkg /Users/USER-NAME/Downloads/SDA.pkg -target /
  • Symphony recommends installing in the "/" (root) volume. To install the package in the root volume, the user needs to run the sudo command.
  • USER-NAME is the local user, for example John.Smith. Replace it with the name of the user for whom the app is being installed.
