Note for anybody thinking they want to use this with Zoom/Slack/Discord/etc: It appears that this has the same restrictions that other DAL-based apps have and you'll need to re-sign the app or disable SIP to use it that way. I've been using an OBS virtual camera for this purpose and have had to do this a few times now. It will depend on the target app if they have this in their allowed plugins list.

On the SIP workaround, it says disabling SIP for the filesystem is enough, but even though that's less broad then disabling SIP entirely it's still a pretty wide brush. Have you (or anyone else) tested whether it's enough to disable SIP just for specific applications or folder locations? IIRC, all definitions and exceptions for SIP fs restrictions are still in two locations:

  /System/Library/Sandbox/rootless.conf

  /System/Library/Sandbox/Compatibility.bundle/Contents/Resources/paths

Disabling SIP entirely allows editing these as root, and then reenabling allows more fine grained control. Of course like everything else in an Apple-owned location, changes have a high chance of being blown away any full system update, but those are rare enough (and always require a reboot anyway) that it doesn't seem like a major pain to just redo changes a few times a year (with a script).

There are still of course some security implications for any additional exceptions you add but a lot less then a full fs disable. Further it's cool to have control over it anyway because you can even extend SIP to additional locations of your own which could be handy for some scenarios.

I can't comment to disabling SIP as I haven't taken that route. I've generally taken the codesign route instead, which does require re-signing the app after every update. In the case of Zoom, that's gone away in recent versions since the app now has the virtualcams I'm using in its whitelist. For anything else, it's a very manual process.
