FAQ Section: Macintosh : Mac OS X
  1. Why can't I export JPEG and PNG?
  2. GIF-Export returns files with no content (0 Bytes)
  3. Why does Poseidon keep using an old JDK even though I have JDK1.5?
  4. I cannot open files - is that a bug?

    This is a problem of the Java version 1.4.1 on Mac OS X, in conjunction with the Aqua Look and Feel. A typical problem symptom is that no dialog appears when you click 'Open File'.

    For Mac OS X, you need the latest Java update. These are the specific requirements:
    Mac OS X 10.2.x (Jaguar): Get Update 1 of Java 1.4.1. Also, change Poseidon's Look and Feel to Alloy - the Aqua Look and Feel produces problems like not opening dialogs.
    Mac OS X 10.3.x (Panther): For Java 1.4.1, Update 2 is recommended. Furthermore, you should also use the Alloy Look and Feel.
    Mac OS X 10.3.x (Panther): For Java 1.4.2, any Look and Feel can be used.
    Mac OS X 10.4.x (Tiger): For Java 1.4.2, any Look and Feel can be used.

  5. Why does Drag and Drop from the tree to the diagrams not work?
  6. Can I use the Eclipse Integration with Mac OS X?
  7. When I click on the Poseidon icon nothing happens.
