7/17/2020 - Latest Teams update breaks Virtual Cameras - Microsoft Teams Version 1.3.00.18164

Mac OS Catalina 10.15.5 - Just prior to today's update on my machine to the above version 1.3.00.18164, Teams was able to utilize my OBS and Wirecast virtual cameras which I use all the time. Now Teams doesn't see them and yep, the permissions for screen recording, etc are all accounted for and I disabled and re-enabled the settings, as well as restarting the app(s), including Teams, etc. and the machine. Previously, I was able to choose the appropriate virtual camera. Now I only have access to the Mac's built-in webcam. Obviously, this is not ideal. Has anyone else seen this defect today (or recently)? Is there something I'm missing besides checking the security permissions, restarts, etc?

 

Thanks!

    Solution for running two separate terminal commands seem to work in here for me.

     

    Please a have a look.

    Found this for another product, and it works for mmhmm:

     

    https://support.ecamm.com/en/articles/4343963-virtual-camera-missing-after-microsoft-teams-update 

     

    Basically, this article suggest removing Teams' code signature

     

    sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Renderer).app"

    I do not know the long term side effects of this, so do it at your own risk.

     

    Good Luck!

    This is of course still broken almost 8 months later. Unbelievable! And no, it's not a suitable option to use browser-based Teams as there's other stuff there that's broken. I continue to need to unsign the app.

     

     

  • eRayHarrison Thanks for reporting this.  We are working on this, and until then, you can use the virtual camera in Teams in a web browser on your Mac.  We will update at the link below when there is more news.

    eRayHarrison My GoPro webcam just broke with this version as well with version 1.3.00.18164. 

     

    Zoom had a similar issue with signed applications and using virtual webcams, but fixed it. I really think this is a Teams issue.

    Just came here to say that this latest update has broken Virtual Cameras for me, as well. I'm on a Mac using Mojave. I was using Virtual Cameras one day and then updated Teams. As soon as I updated Teams, my ability to use Virtual Cameras went away that same day. I'm currently using Microsoft Teams Version 1.3.00.18164.

    This is also affecting me--  The ability to use virtual webcams for complex output (CamTwist and Iruin Webcam) is disabled; as a college instructor, I need webcam capability.  I hope that this bug is addressed quickly.  It is directly a Microsoft Teams update issue; other software on the Mac is not affected.

    Temporarily, I was able to completely remove the updated version and was thankfully presented with the slightly older version 1.3.00.15561 which restored virtual camera capabilities. I've worked to fuddle up the teams updater daemon to hold off for a couple of versions to hopefully have the functionality restored.

      eRayHarrison Would it be possible for you to post instructions for how you successfully downgraded and are blocking the auto-update for now?  Thank you!

        AndrewBonham Did you ever get any answer to how to downgrade Teams for Mac to a version that doesn't break the OBS Virtual Camera? 

         

        I can get the OBS Virtual Camera to show up and operate in the preview devices, but as soon as I connect it freezes.

    Have a look at this thread. Its for an entirely different app but it might provide some insight into the root cause of your issue as it relates to MacOS Catalina and virtual webcams not working after an update.

      hackerx I can confirm unsigning the teams app doesn't enable virtual webcams. 



      sudo codesign --remove-signature /Applications/"Microsoft Teams.app"



      Does not do anything after restarting the system.

        I can confirm that it is a Teams issue only. If you install an older version of the app it actually fixes the issue, but then it breaks again within 24hours because Teams auto-updates (which you cannot turn off). 

         

        Microsoft, please fix this. You have made Teams worthless for those of us who have to do trainings with multiple cameras. This breaks Teams for many in the tech and EDU community.

      hackerx I appreciate the link! Attempting some of the recommendations did not address the issue, unfortunately. This appears to be directly related to the MS Teams update as the functionality was working directly prior to the update and not working after the update, with no updates to the OS or other Catalina-specific software in the interim.
