Minecraft Forums

I've got a Mac running OSX 10.5.8. I'm trying to get the newest version of MCPatcher for the newest versing of minecraft (1.6.2). when i double click on mcpatcher-4.1.0_04.jar i get this message...

The Java JAR file "mcpatcher-4.1.0_04.jar"
could not be launched.

Check the Console for possible error messages.


This is the error message I could find...
