Catalina update 10.15.7 broke webcam in Google Meet (Chrome and Safari)

Blackmagic Web Presenter makes SDI and HDMI video equipment appear as a USB webcam. It was working fine for months on Sierra (2009 iMac) and Catalina (new iMac) until Mac OS 10.15 was updated recently to 10.15.7. Now it keeps disconnecting. It did this previously only once in a while. Now it happens every second as shown in this video: https://vimeo.com/546630238/117d731dfc


It happens in both Safari and Chrome. I can get the Blackmagic Web Presenter audio input to stay connected only if I turn off the camera in Google Meet. It works better in Zoom but still disconnects every few minutes.


We are heavily invested in BM ATEM and Converters. Web Presenter is the core equipment that enables us to do have virtual participants in our venue and as an educational environment, Google Meet is the core video conferencing.


Any ideas to resolve this issue?

Hey Ernest House,


Thank you for the update. Since this began only after the macOS update, there may be an update that is needed for the webcam from Blackmagic Design.


Are other USB devices working when connected to the computer?


If the issue is isolated only to this one USB device, you may need to contact Support Center | Blackmagic Design directly.


Keep us posted.
