I'm also using an E m5 mk2 on macos, with the battery holder grip and 25mm lens. I'm happy with the image but the software is pretty bad, isn't it? There's a substantial lag between the audio and video which is disconcerting to the viewer. And the video stream doesn't reliably start. I usually have to flip the video off and on a few dozen times in the Zoom app before it begins working.
Aside from that the cost of the Very Special USB Cable is a real insult.
