Working on Mac OS X apps

[aldente]

Hi there!

I just installed OS X (x86) on my machine, next to Win XP. Looks like a really nice operating system.

But unfortunately there is nothing like OllyDbg (at least I didn't find anything) to examine OS X apps

I also tried to disassemble the apps with IDA, but that does not seem to work either.

This is such an application (bare main-application, extracted from the .app-Folder). It is an Universal Binary, so it runs natively on x86 and Power PC platforms.

If you know how to disassemble this properly, or if you could give me any hints for a good debugger, please help me!
