Denafrips Aries II and Mac laptop issue

hi all

Recently got a Denafrips Aries II and I am trying to use it with my Mac laptops, both running latest MacOS Big Sur.  I seem to be having issues where the laptops either freeze up or become super slow when I connect the unit via USB. Sometimes it works, but then when i disconnect and reconnect Mac does not detect it anymore and the same problem repeats. 

I just installed the latest firmware too last night. Initially I thought it helped. But the same issues came back soon. Has anybody had this experience? I see this with both my laptops, one is older and other is very new.  Not sure if this is a Big Sur compatibility issue.

I primarily use Mac for my listening and if I cant get this resolved I will have to send the unit back.

Many thanks!

Hey guys, 

Please reach out to me should you experience USB compatibility issue with Mac. A firmware update of the USB MCU is required to fix it. 

Cheers,

Same issue here annoying, I thought my Mac was dying. So far best Solution is to just leave the DAC on all the time. Thanks will contact you for update firmware

@maelob - that is a different issue, and it's one that I told Alvin about a while back (and he said that no one else ever had that issue). Yes, if you unplug or re-plug in the Ares II, it will kill the Mac, requiring a power down and re-boot. That problem has existed since I first received the Ares II; I don't know that it is an Ares II bug (vs. a macOS bug), but none of the other 100x devices that I've used with a Mac have caused this problem.
@alvin1118 - I also shave the *new* USB issue with Big Sur. Sent you an email today. Is there a link to the fix that you can just fix publicly?

I also have weird issues with the Ares II and my older Macbook pro (which I will be most likely updating this year).  I need to make sure the DAC is selected for USB first before plugging in, or it freezes the macbook or my iphone, and I have to restart.  Then it usually works fine.

Also, I'm running Mojave, as a couple of my music interfaces were not working with Big Surr.
