DHCP Setup for Macintosh OS X

The default installation of MacOS X has all of the necessary software you need to use your connection to connect to the Columbia network. This document describes how to set up your Mac running OS X for use with a DHCP connection on the Columbia campus. Before following the instructions in this document, make sure your ethernet cable is plugged into the correct wall jack, as well as the correct ethernet port on your Macintosh. This guide assumes your Mac has a properly installed ethernet card/adapter.
If you have not used your Macintosh on another network, chances are that if you plug in the network cable it will work without additional configuration/installation. After you plug the network cable into the jack and the computer, you may need to reboot the computer, depending on your configuration. If your connection doesn't work after this step, you will need to follow the directions below to setup your computer for DHCP on the CU network.

Step 1: Boot up your Mac. When presented with the desktop click on the System Preferences icon in the MacOS X dock.

Step 2: Now, click on the Network icon to open the Network Preferences panel.

Step 3: Once in the Network Preferences panel, change the Show drop menu till it displays Built-in Ethernet. (Depending on your Mac version this may be called "Ethernet built-in", "Ethernet", or some version with the word "Ethernet" in it.) Now, change the Configure menu to Using DHCP. Everything else in this box should be left blank (see below for what the preferences box will look like) When you are finished, click Apply Now. Your network configuration will now be applied to your system. Finally, close the network preferences box.

Step 4: Your computer may ask whether you want to save the current configuration, click Save.
