It's a grandma2 with eth0 with manet2 network (192.168.0.11 and Mask 3x255.0) and eth1 with artnet network (2.4.1.1 and mask 255.0.0.0). Catalyst was 2.1.1.1 mask 255.0.0.0. I dont think it's bad because it work with MacBook pro with réel ethernet connector and with Mac pro. The problème is just with new Macbook pro Retina with Thunderbolt adaptator
