How to Share a Mac Internet Connection

This process shares your internet connection with your other computers and mobile devices, so you need an Ethernet network adapter and a wireless adapter on your Mac. You can use a wireless USB adapter to add Wi-Fi capabilities to your Mac.

  1. Open System Preferences and choose Sharing.

  2. Select Internet Sharing from the list on the left.

  3. Use the drop-down menu next to Share your connection from to pick your internet source, such as Ethernet to share a wired connection.

  4. Below that, choose how other devices will connect to your Mac.

  5. In the left pane, put a check in the box next to Internet Sharing.

  6. When you see the prompt about sharing your Mac's internet connection, click Start.

  7. Read any "warning" prompts if you get them, and click through with an OK if you agree to them.

Tips on Sharing Internet From a Mac

  • If you're using AirPort, enable wireless encryption by clicking on the AirPort Options button and checking the option to allow encryption. Although it only uses the inferior WEP protocol, the WEP encryption (choose 128-bit key length) is better than nothing.
  • You can change the channel to minimize conflicts with other networks and also choose a unique name for your system.
  • If your host Mac computer goes to sleep or shuts down, any connected clients will be disconnected, and no new clients will be able to find the connection until the computer turns on again.
  • Stop sharing your internet connection by removing the check in the box next to Internet Sharing at Step 5.
