Hello
I am currently using the with AppleTV. If the Mac Book outputs audio via HDMI, this should also work.

Hi, I am very satisfied with the extractor. I have connected all sorts of things via the HDMI (In) and everything was extracted without any problems! 👍🏻 AppleTV, Swisscom TV, PS5...all great! Unfortunately I haven't tried the MacBook but it shouldn't be a problem. Greetings
