Note: The Conferences i/o Mac App is in public beta. While the app has been tested by many customers, there can still be quirks or bugs that have not yet been ironed out. If you are using the Mac App and see any strange behavior, please email


Live content slides are not loading when in presentation mode

Follow these steps to troubleshoot missing live content slides during presentation mode.

  1. Ensure the Mac App is running by locating the icon in the menu bar

    If the icon is not present, run the app. For more information about opening applications, see the Apple user guide.

  2. Ensure the Mac App helper is enabled by clicking the menu bar icon and verifying the status icon is green

    If the icon is yellow, click the Enable button to re-enable the helper.

  3. Verify that you have the latest version of the app

    Due to changes in macOS 10.15 (Catalina), any 1.3.x or earlier version of the Conferences i/o Mac App will fail to display live content slides. While the App will appear to be running in the Mac status bar, you will not be able to run polls or other live content while presenting.

    You can find the latest version of our Mac App here.

  4. Double-check that the slide code is properly set on the slide:
    1. Sign in as a moderator on the desired session then click Session Settings
    2. In Session Management under Presentations, click Add Live Content to Presentation Slides
    3. Locate the slide desired slide content and copy the slide code
    4. Paste the slide code between the <cnf> </cnf> tags in the presenter notes section

  2. On the display with presenter view, click Swap Displays


  3. Move to a different slide in the slide deck, then move back

The live content slides do not respond to input from remotes, keyboards, or mice

  2. Disable or close other polling software add-ons or applications
  3. Re-start the presentation

The Mac App no longer works after a MacOS reinstall (upgrade, in-place, or downgrade)

  1. In System Preferences, open Security & Privacy
  2. Click the Privacy tab, then scroll down to Automation
  3. If necessary, unlock the preference pane.
  4. Locate the Conferences i/o app in the list and ensure all of the boxes are checked
