I'm getting the same "command not found" problem that Kongwubba was, but I have replaced the {FILE NAME HERE} with Technic and it still doesn't work.
My technic_launcher.command:
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home java
-Xmx1024M -Xms1024M -jar ~/Desktop/Technic/TechnicLauncher.jar
What am I missing?
