USB to SPIDIF converter for MAC

Looking for a USB to SPIDIF converter that works with the latest MAC OS and one that handles higher resolution like DSD or 192/385 

I’d also be interested in any input/options for a server that dosent rely on a network connection but will work with a separate hard or NAS drive 
Schiit Audio Eitr.   Great product and value - It’s what I use for the same purpose in one system.  Please note it only goes up to 24/192.  

Singxer SU-1 is what you are after if you require higher rez than the Schiit Eitr.
