After installing Java 7 there are at least two Java installations available on Mac OS. When running Java the operating system follows a link to the version currently marked as default. In some cases this link still points to the Java 6 installation despite having a functional Java 7 installation.
Open a terminal and navigate to the directory /System/Library/Frameworks/JavaVM.framework/Versions by typing:
Make sure that you have a valid Java 7 installation before changing the link to the current version. You can do this by typing:
The output should start with “java version 1.7…“ . If it does not, do not continue with the following steps but rather see “What is Java and how do I install it?” for instructions on how to install Java 7 on Mac.
To modify the link to point at the Java 7 installation type in the following two commands (you may have to enter your password):
sudo mv Current CurrentBackUp sudo ln -s A Current
Mac OS should now use Java 7 by default.
Hint: To switch back to Java 6 type in:
sudo mv CurrentBackUp Current
