A:AnswerIt should be. I'm not running a Mac (I have Linux), but the device shows up as another video source in OBS on Linux and Windows. I'm sure it would be the same for Mac. Documentation says it works with all three.
A:AnswerWe are presently trying to replicate these results. This may be related to an HDCP block, so please make sure there are no apps that would have HDCP enabled running in the background. This could include Movie/streaming apps or the DVD/Blu-Ray player.
