If your Mac supports Bluetooth you could connect it to your NDX this way. SBC (AAC) might be enough for Apple Music content? naim devices also support aptX, but I haven't gotten this work reliably with my MBP. I can see aptX is used for the Bluetooth connection, but it is unstable and hence not usable.
Question to naim - are there plans to support Apple Music directly as Sonos now does?
