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!

It says file not found

Any ideas what I’m doing wrong?
Ok I worked it out. I’m not used to windows it’s like a foreign language. So I had to extract it first which I thought it was doing anyways. 
I am having the same issue. The firmware update looks very complicated, especially for a non-PC user (I won’t even get into the issue of having to find a windows laptop to do this).

olivermeyet, any tips that will help me avoid the issue you had?
