I am unable to launch the 1.5.1 IDE for OSX on my MacBook Pro, which I want
to do in order to use a new Arduino Due.

Mac OSX 10.5.8
$ java -version
java version "1.5.0_30"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_30-b03-389-9M3425)
Java HotSpot(TM) Client VM (build 1.5.0_30-161, mixed mode, sharing)

I tried Java SE 6 as well, no help.

I tried using "control click" and open, no help.

I tried moving the icon in and out of my Applications folder.

My older version of Arduino (1.0.1) works fine (I have renamed it ArduinoOld and moved it out of my Applications folder).

I don't have any default hardware folders (that I can find).

On the console i get this message, which I don't know how to interpret:

Any suggestions appreciated.

I don't have any default hardware folders (that I can find).

Have you looked in
Documents -> Arduinio
the folder is called hardware just above the libraries folder.
If you have it just rename it something else, I rename it "hardware hide"

[Reply #2 on:]

yes, thanks, i saw that in another post and looked for it but i don't have any folders named hardware

OK what console are you seeing that error message on?

[Reply #4 on:]

i launched the "Console" application from Applications/Utilities on the MacBookPro, since I didn't have any other diagnostics (the Arduino icon just goes poof and doesn't send any messages).

resolved:
--fixed Java so Java SE6 choice pointed to proper directory for CurrentJDK, and
--built explicitly using the github ide file Arduino-ide-1.5.x
