iPhone hotspot prioritized over ethernet In Yosemite, when I connect my iPhone to my Macbook Air through USB the iPhone becomes a internet hotspot for my Mac, even though I've connected the MBA via ethernet. If I enable Wifi, then Wifi is prioritized.

Can I change so that ethernet is prioritized over the iPhone?
