I'm writing this question on my iMac. It's connected to the internet via WiFi as my modem/router is in another room. My iMac has bluetooth running for my magic mouse and apple keyboard.
I've also got a PC here at home, running Windows 8 (I'm an MSDN subscriber) and it has a Bluetooth adapter and an ethernet port.
Currently, I can't connect the ethernet adapter because we're waiting for the wiring to be connected up.
Can the Windows PC share the Mac's WiFi internet connection via Bluetooth?
