Dukeblue: Getting connected on Mac OS X

Duke University has implemented a secure wireless network known as Dukeblue which uses the authentication mechanism WPA-2 Enterprise and 802.1X. When correctly installed and configured, this network can protect your Duke NetID and password, and ensure your data and transactions are secure and protected. 

In order to connect to the secure network, adjustments will need to be made to your computer network settings. This process is simplified through the use of an installer. Follow these steps to configure your Dukeblue connection for Mac OS X so you can take advantage of this layer of security. This article was created and tested using a computer running Mac OS X 10.9.4 and was reviewed on subsequent releases up to Mac OS X 10.11. You must be running Mac OS 10.5 or greater to install this software.


  1. Connect to the Duke wireless network. 
  2. Go to https://launch.dukeblue.duke.edu and click the JOIN Secure Wireless Network link.
  3. The web page will display information about your computer including the operating system and version number. If this information is incorrect, select your computer OS version from the pop-up menu at the bottom of the page. 

  4. Click the button JoinNow which will download the software SecureW2_JoinNow.dmg installer.

  5. Within your Downloads folder, double-click the SecureW2_JoinNow.dmg which will mount the installer and open a new window. Double-click the SecureW2_JoinNow application. If you receive a warning that the application is downloaded from the Internet, click the Open button.

  9. Click Done to complete the installation and verify your wireless connection is set to DukeBlue

NOTE: You should routinely verify that your wireless connection has joined Dukeblue. In any given location, a large number of networks are available and your computer may not default to Dukeblue.
