Unable to Join a Meeting on Mac - Hangs at Meeting In Progress

Unable to join a meeting on a Mac - hangs at Meeting In Progress.

I can't get past the Meeting In Progress page when starting a meeting on a Mac.

'Cisco Webex Add-On Required to Join Meetings' when joining meeting from Mac OS 10.10 or later.

Nothing happens after I click 'Install' on the 'Cisco Webex Add-On Required' prompt.


The latest versions of Safari use a plug-in manager for enabling and disabling plug-ins on a global or per site basis.


To resolve this issue trust the Webex64 General Plug-in Container.

To trust the Webex Plug-in for Safari:

  1. Choose Safari > Preferences > Websites.
  2. From the left panel, under Plug-ins, choose 'Webex64 General Plug-in Container'.
  3. For all sites listed on the right, select On.
  4. Next to the option for 'When visiting other websites', select On:
    User-added image
  5. Quit and restart Safari.
  6. Try to join or start your meeting again.
