As of October 17, 2012, Apple removed the Java Runtime Environment from Mac computers running OS X 10.7 (Lion) and above. Computers running OS X 10.6 and below still come with Java pre-installed and will work fine with Java-based applications. 

The removal of the Java Runtime Environment affects all web browsers installed on your Mac (Safari, Firefox, etc...) and will cause problems with Collaborate and other NAU websites that rely on Java. Google Chrome is not currently supported by Java so ITS recommends that you use Safari or Firefox to access Java-based applications. 

In order to remedy this you will need to install the Java Runtime Environment onto your Apple computer manually. To do so, please visit www.java.com:

Alternatively, you can wait for a website to prompt you to install Java and follow the instructions below.

When prompted by a website to install the Java Runtime Environment, click the More Info... button to be redirected to the Java download website. Clicking OK will close the popup and do nothing. Be sure to click More Info....

Click the button that says "Agree and Start Free Download" in the middle of the Java page. Once the file is downloaded, double-click on it to open the downloaded file.

Double-click on the icon one more time to begin the installation process.

Once the installer has started, proceed through several installation windows in order to install Java on your Mac. You may be prompted to enter the password to your computer; be sure to enter that password if prompted.

Once you see the Install Succeeded message, you are finished installing Java. Click Close and restart your web browser. Once you have opened your browser back up, try navigating to the site that you were on before and verify that Java is now working. Alternatively, you can visit this website to verify that Java is installed correctly:
