I had a need to link the wifi of the iPhone to my macbook via USB. Is it possible? It didn't appear to be. Reason for doing so was an odd one. A few free wifi places in China need wechat login to gain access to the free wifi. I have wechat on my iPhone, so it connects no problem. If you connect to the free wifi on the macbook, then safari sits with a QR code on the screen and nothing else.
