This was stopping the obs virtual camera working.ĭeleting the signature from Skype meant that this extra level of security was disabled allowing the obs virtual camera to work. It turns out that hardened applications can tell the OS that they only want to use libraries signed by Apple, or the same developer. I came to this after following a link in other discussions about how various apps were disabling virtual cameras through application restrictions. I'll also repost the commands posted by OliFrieda for your convenience. This was already posted by OliFrieda earlier, but I think people will appreciate the reason why this works.
What worked for me on Skype, with both preview and real video chat, was deleting the code signing on Skype.
