I'm sure this is possible but I can't figure it out. Im networked between a couple of my macs but was wondering if there is a setting that makes the network ethernet only. Right now Im connecting them using both Airport and ethernet. Whenever I need to connect both computers, and I am using the Airport on my laptop and need to transfer large files it networks over wifi instead of ethernet automatically. Basically if I am connected wifi first it assumes I want to share over wifi instead of ethernet. Trying to save myself the hassle of turning off my airport on my laptop before I connect through ethernet to share files. Plus to give me piece of mind that no one can connect to my macs as well. Hope that makes sense.
