Install Java for MAC OSX 10.5 (Leopard)

  1. Updates to Java are included in Mac OS X's Software Updates. If you are running an old version of Java, you should use the Software Update tool to get the latest version.
  2. Once you have updated, follow the instructions below for making Java 6 the default installation.


Make Java 6 the Default

  1. Open the Java Preferences utility which can be found by going to "/Applications/Utilities/" or doing a Spotlight search for "Java Preferences".
  2. There should be two lists present in the Java Preferences window - the top one is labeled "Java Applet Plugin" and the bottom one is labeled "Java Applications". In the bottom window, click and drag the version named "Java SE 6" to the top if it is not already so.
  3. Exit Java Preferences.
  4. Open a new terminal window and repeat the "Checking to see if Java is installed" section to make sure everything works.
