While I don't have ANY experience with this particular issue, I'm told (as you yourself said) that the Dev Studio is as of this moment 'supposed' to be OS independent, and should (and according to you, does) work on Linux and Mac OS's....so the questions I'm asking are more of a basic type of level.
Are you running the latest Java for MAC?
You mention 7.6.02.02....but I'm not familiar with that version...I know there was a 7.5 and a 7.6.03 and a 7.6.04, so if you could clarify your version, it would be appreciated.
Regarding that...I suspect that the .02 at the end is the patch? Have you tried it with the latest patch? 7.6.4 is up to patch 3 at the moment. This might even be a possibility for you even if you aren't on 7.6.4
