• try epoccam?

    ..ha did not know something like this exists, thank you!

    Took me a while to make it work on Catalina even after jumping through the hoops as detailled on their support page (as seen below, for anybody finding themselves in the same spot), restarting app / phone, restarting mac / app, and manually killing it in activity monitor..
    ..but now it seems to work; will probably buy the full version.

    Doesn't work with apps like Zoom, SnapCam, Skype for Business on macOS
    Recently many macOS application have started enabling security feature called library validation. This disables using virtual webcams like EpocCam. You can leave feedback to application developers to bring back support for virtual webcams but there is also a workaroud. You can remove signature from the app allowing it load again load third party libraries such as EpocCam plugin. Here is video how to do it using following steps

    Install Xcode command line tools via Terminal.app by typing: xcode-select --install Remove application's code signature with Terminal.app, for Zoom type: sudo codesign --remove-signature /Applications/zoom.us.app/
    Quit and relaunch the app with signature removed, it will now detect EpocCam
    Similarly if you want to remove signature from SnapCam, type: sudo codesign --remove-signature /Applications/Snap\ Camera.app/
