Virtual Camera Driver Stopped Working After a Site Upgrade

Cause:
As part of hardening the security of the Cisco Webex Meetings Desktop App, the macOS clients had the following entitlements removed:

• Disable Library Validation Entitlement
• Allow DYLD Environment Variables Entitlement

As a result, many virtual camera software applications stopped working because the webcam drivers they use are not signed by Apple, and thus cannot be loaded by the Cisco Webex Meetings Desktop App.

Affected Releases:

• WBS40.7.0
• WBS40.6.0
• WBS40.4.3
• WBS40.2.16
• WBS39.5.23

Solution:
Virtual camera software applications and drivers are no longer supported by Webex Meetings and Teams.
