hi i can not use the enttec usb pro mk2 with millumin v3 in Big sur osx 11.6 ! is it because there is no PRO-Manager application to osx 11.6?
I just tested the Enttec USB Pro Mk2 on a MacMini running macOS Big Sur 11.6 : it is correctly detected by Millumin.
Is your device working with another software ? If not, I recommend you to contact Enttec support to check if they are aware of an issue.
