I have got a very new MacBook, originally it had OS X 10.7 (Lion), I upgraded to MAX OS X 10.8 (Mountain Lion).
I installed Java version 6 (64 bit), Java 6 (32 bit) and Java 7 (64 bit).
I download karatasi.java version 0.4.0 beta from SourceForge, the DMG version for MAC OS.
I extract karatasi.app from the DMG package.
I try to start it, but get the error message "karatasi.app is damaged and can't be opened. You should move it to the Trash."
