A lot incorrect in this answer Neil. Resolve has an in-built software renderer, (but you need the Studio version to use it.)It can then decode Atmos and play it back through your specified configuration of bed and height speakers. An Atmos Bed does sometimes have Height channels, bubt usually you height speakers that will play back objects that move into the 3d space tghey are outputting. You don't need a LOT of hardware to play back the decoded content; a 16 channels soundcard, or de-embed from the SDI of a Decklink. But a lot of confusion exists about this and consumer atmos, which is object based metadata to extract a limited number of 3d objects from the standard 8 channels bed in the HDMI stream. You need a software decoder, or correct bitstream output to an Atmos docoder in an AV amp for that. Still don't hink you can do that at all on a mac, but I may be wrong, it might just work on an M2 laptop, but I think they disable it
