Mac Internet sharing doesn't show wifi option (only Thunderbolt)

Thanks for your reply.

There are two scenarios when I need it( they are a bit tricky tbh and both related with embedded network development).

1. I do a development on boards which needs Wifi (access point with SSID/PASSWORD), but there are some Wifi security systems when you have to login to some web page(sometimes they show some ad or smt. like that during it) and after that you can get access to Wifi network, as there is no way to do that steps in board you can't get access to that network. (May be there is a way which I don't know)
2. When you want to see a network traffic for source and destination IP addresses (but your server is not a PC and destination address can be another board for example), you can't access to that interface and see a network traffic. So you have to serve PC as a router and share your network, in that case you will be able to see whole network stream.

Hope I was manage to describe the scenarios more or less :)
