With Mac ASIO it's only supported by just a handful of DACs and I'm not even sure if any players support native DSD playback via Mac ASIO driver (I do know MC currently isn't one of them - try doing a search of the MC 22 and 21 for Mac forums for ASIO for more info). Otherwise DSD via DoP works fine on Mac (and Linux for that matter). But I think this discussion has deviated this topic enough - it's a discussion for another time (and proper topic, IMO) instead of hijacking this one.

The highly regarded exaSound DACs support ASIO and exaSound's George Klissarov has written an efficient ASIO driver for Mac (I believe HQPlayer supports it too, though I may be mistaken). Among other claimed benefits that some members here have disputed, his ASIO driver's efficient processing allows native DSD 256 to be processed without being converted to PCM. This is not a minor benefit.

I have been requesting that ASIO support be incorporated in MC for Mac since 2015. Obviously (based on the thread Awesome Donkey's quote is drawn from) I'm not the only one interested.

So I respectfully renew my request to the MC team: please add support for the exaSound ASIO driver to MC for Mac as soon as possible!

I second this request.

I'm not against ASIO support on macOS, but DoP is not a conversion to PCM.
It's the exact same 1-bit audio data transmitted inside a different container.
There's zero difference between DoP and Native DSD. Use whichever your DAC supports, and if it supports both it doesn't matter which one you use.

Airfla:
DoP on a Mac only supports DSD128. Native DSD must be used for DSD256 and that requires an ASIO driver.

Awesome Donkey:
An ASIO driver on macOS is only available for exaSound DACs, otherwise DoP is the only option. If ASIO support on macOS is on JRiver's to-do list, it's probably very low on that list due to it only being available for exaSound DACs.

Also, I'm not aware there's a DoP limit on macOS with Core Audio, other than what the maximum sample rate supported by the DAC is (which the higher the sample rate supported, potentially the higher DSD formats supported via DoP). Unless I'm mistaken, at least up to DSD256 (DSD 4x) should be doable on macOS assuming the DAC supports a high enough sample rate allowing DoP to work. But DACs allowing DoP that high might be kinda rare. ;)
