Hi - I am having the same problem, on a Mac Pro running Mojave. I upgraded to 7++ and wanted to use gigabit ethernet instead of firewire. Plugged an Ethernet 5e cable into Expansion Port B of my Pacarana, and into the gigabit ethernet port on the Mac - no adapters required. Kyma 7++ is not recognizing any Pacarana connected to the computer. Thanks for any advice!
