iFi iPurifier2 Problem in the Context of macOS/OS X

[aschaub]

Hello,

 

I have a 2013 iMac running High Sierra and run that into a Triode Audio Company TRV-CD5SE vacuum-tube CD player and USB DAC by way a of a Stealth Audio USB 2.0 cable (USB A to USB B).

The sound is great, but I wanted to see if the iFi iPurifier2 would make it even better, so I borrowed one (the USB 2.0 B model, not the USB 2.0 A model) from a friend, but it's not really working.

When I plug it into the USB 2.0 B input of the TRV-CD5SE, all of the Purifier2 lights come on but my iMac can no longer "see" the TRV-CD5SE at all.

I can try another USB 2.0 cable. I have a few extras. I'd just really like to use the Stealth USB cable and I have a feeling it might have to do with High Sierra (macOS / OS X version 10.13.6), which seems to have a lot of bugs with disk formatting and USB 2.0 support; although, the firmware in the iPurifier2 might need an update, too?

Any and all suggestions would be greatly appreciated.

 

Cheers,
Andy

Silly question, but why are you running High Sierra?  I'd upgrade your Mac to the most current OS (Mojave) at no cost and just see if that fixes your issue.
