I'm trying to get Java 1.5.0_13 on my Mac for OS 10.4.10. I found the download at apple.com, which is where the Java/Sun linked me to go. Then I downloaded the pure java version of the Wyvern Map editor and after I downloaded Java it still says I need Java 1.5.0_13.
Currently I have 1.5 and 1.4, which is enough for the regular pure java Wyvern application, but not for the Map Editor.
Here is the link to the Java download.

Has any mac player/wizard tried to download it and install? When I try and open the map editor it still says I need to update Java.
