Help! On my MacBook Pro running 10.13.6 I have downloaded OBS and NewTec NDI (Video Monitor, Virtual Input) and the NDI camera and capture apps on my iPad and iphone. I've also added the NDI runtime, NewTekNDI Tools and NewTikNDI Driver. That said, in OBS when I select the NDI input from phone or ipad, nothing show up in OBS. What am I missing?
