First of all, the mac must be running Tiger (OS x version 10.4) or
better. Once this is true you need to ensure that the Mac has Java
1.5 installed To check the version, open a command line window and
type "/usr/bin/java -version". There are three possibilities:
1. you get something like "command not found". Actually I am not
sure if this is possible but if it happens it means that you need to
install Java 1.5.
2. It will report an earlier version of Java. In this case you need
to install and/or configure the computer to use Java 1.5. You can
find infomration about getting Java 1.5 on the apple site (http://
3. It will report Java version 1.5 in which case you are using the
right version of Java.

It does work fine on a Mac. I use the Mac as my main development
> PS there is no java 1.6 for protege, is there?
We don't support Java 1.6 yet because - unless you pay up to be an
apple developer - there is no Java 1.6 for os x. I have already
heard some reports that Protege doesn't work properly with Java
1.6. We will move to Java 1.6 sometime after the apple makes java
1.6 available for os x.
