Neat Trick: Two Laptops, One Without Wi-Fi?
I was recently with a buddy whose corporate laptop doesn’t have wifi, and it occurred to me to see if I could share my EVDO connection with him. Guess what? The sharing preferences on your Mac make this task a two-click process.
Connect to the internet with your mac, and you can share that connection seamlessly over ethernet, firewire, or even wireless.
I guess I always knew this was possible, but I’d never realized how convenient it was. Give it a go.
