Hey everyone,
It seems that Skype, Zoom and a bunch of other applications had to enable something called library validation. This can be seen here: Library Validation
The problem here is, for example, with Zoom, this restriction blocks any plugins that aren’t digitally signed by either Apple or Zoom to not function.
In the past, the Google Chrome team added a way to securely move the webcam capture module to a new process and then they removed this restriction for that process.
This is why ManyCam can now function with Google Chrome on MacOS but not Zoom and such. We’re trying to get in touch with Apple, Zoom, Skype and anyone else that has this issue so we can try and resolve it for everyone. This is a problem that affects not only ManyCam, but anyone who develops virtual webcam software.
We hope that we can have this resolved soon for our MacOS users and we’re working on this problem from a bunch of different angles.
