I'm using your MMB 10.9 videos to take the MMB 10.10 exam. I'm on the Deployment episode and am following along doing my own lab work on my Macbook Air. I'm using VMWare Fusion to create virt machines to install my created nbi images to. I'm in the NetInstall Server Admin and am trying to "Enable NetInstall on:" an interface, but my Macbook Air has no interfaces. How do I add the network interface to install to my virt machine?
