AirDrop: Why is WiFi necessary?
Why did Apple not allow Airdrop to operate over ethernet on a local network? I have a WiFi network running from an Apple router at home but I have a desktop hardwired to the router. To get Airdrop to work between the desktop devices in the Wifi network, I have to turn on WiFi on the desktop? Why? Seems a little inconvenient. I'd rather not have so many comms paths open.
