Mac OS X cracking

ah finaly i got one of those favourite JMI replys
well perhaps my first post wasn't clear enough...i have searched the net
for those kind of tools...but all i found wasn't really helpfull...macnosy is
only for os9 and not updated to X...then you can use ddd together
with gdb, not really helpfull too...

what i would like to have is some info what are the common tools for cracking
on mac os x. you find really much if you search for the windows plattform
including essays but nothing for mac...
