I need to show some demonstrations at an upcoming conference where I run a node.js server on my machine, and let the audience connect to it (I'll give the IP address).

The "Internet Sharing" capability of OSX works great if my MacBook have the Internet connection (via Ethernet), but that option is not available if it doesn't have the Internet connection.

All I need is a local (isolated from the Internet) WiFi connection between my MacBook and audiences devices. I'd really appreciate if somebody could help me to solve this issue.

1 Answer 1

Take a small switch with you so you get a connection to a Network. Then configure that network manually and everything should be up and running.
