Mac Livestreaming with OBS

To get OBS virtual camera or NDI to work in some video conferencing software you must disable library validation.

• johnboiles/obs-mac-virtualcam#4 (comment)
• https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_cs_disable-library-validation

Typically, the Hardened Runtime’s library validation prevents an app from loading frameworks, plug-ins, or libraries unless they’re either signed by Apple or signed with the same team ID as the app. The macOS dynamic linker (dyld) provides a detailed error message when this happens. Use the Disable Library Validation Entitlement to circumvent this restriction.
