Installing Java 6 on OS X Mavericks, again.

I needed to have Java 1.6 run on OS X 1.9, Mavericks. I had written about this before in Installing Java 6 on OS X Mavericks, but I was not confident with the solution. Today I decided to install Apple's Java 1.6 and see what happened. Would I have have to rebuild my whole machine? No. Nothing bad happened and so far so good. So, to install Java 1.6 do the following:

Download and install Java 1.6 from and install.

Set Java 1.6 as your default using

/usr/libexec/java_home -v 1.6

For more information on java_home see
I need to use NetBeans 7.3.1 (newer versions require Java 1.7) which is downloaded from

To ensure that NetBeans runs using Java 1.6 edit the configuration file


-- which is actually a bash script! -- and define the netbeans_jdkhome environment variable

netbeans_jdkhome=$(/usr/libexec/java_home -v 1.6)

And that is it. You now have Java 6 and Java 7 on your Mac. If you want Java 1.6 to be the default for you always then add the following to your rc script

export JAVA_HOME=$(/usr/libexec/java_home -v 1.6)
