Happy Holidays!
If you have Kyma 7+ already installed, then it should just work (after you connect a gigabit Ethernet cable to Expansion port B on the Pacarana). Otherwise, you may have to update to the latest version of Kyma 7+ for Ethernet.
If you are using macOS 11 or newer, then you should install Kyma 7++ (which is universal for Apple Silicon and Intel Macs)
