Hi ! I asked a simple question and I came to the conclusion that Apple's hardware worth even a few thousand dollars can only output audio ac3 / dts over hdmi because it does not support bistreaming, even needed for new audio tracks eg. atmos or dts: X. All new mac can decode h265 4k but can't play atmos, dts: x audio track, what can they do chap box with chinese !! Bottom deleted post: ".. Why not ? Any from Apple stuff can't read this forum ? So why is it branded the apple community? Does not matter. Let your Apple offers computers that only give ac3 / dts for the price of several thousand dollars, good luck! BTW: Installing Windows on mac is not a solution, since macos is such a great system. .." Reg.
