Tethering your computer will allow other devices to share your computers internet connection.

To do this on Mac OS X, you will need to open your ‘System Preferences’ folder, and hit the ‘Sharing’ button. It’s under the “Internet & Wireless” category.

If your computer is connected to the internet through more than once source, you must specify what source you want to share your internet connection from, under the “Share your connection from” tab. (Ethernet, FireWire, USB Modems, etc)

If you want to share your internet connection wirelessly (via AirPort), you should hit the “AirPort Options…” button to secure your network.

 

Unsecured networks make it much easier for internet predators to monitor what you are doing on the internet, especially if you are not browsing on a https:// protocol. To read more about wireless security, click here.
