@richard1 - You should turn on audio input and camera and not disable library validation. You then should resign the ZoomSDK either by adding a build step or manually in the terminal.
You do that like this.
codesign --preserve-metadata=entitlements --force --deep -o runtime --sign “<NAME_OF_APPLE_DEV_CERT>” ZoomSDK/*.app
Hope that’s helpful.
Cheers,
Tim
