I have been running an ATEM Mini Pro now for a couple of months. I've used it for live streaming on my MacBook Air M1 Big Sur 11.5.2 through OBS 27.0.1 to Youtube. It all works fine except I have problems loading the ATEM Mini Pro as a video source. I first have to deselect the ATEM Mini Pro (it shows up as "Blackmagic Design"), select "FaceTime HD Camera", then select the ATEM Mini Pro before OBS recognises the video input. Otherwise the scene remains blank. Does anyone have any advice on what I can do to get OBS to recognise and load the ATEM Mini Pro automatically?
