Apple Technical Note TN2124: Mac OS X Debugging Magic.
This technote describes a number of 'secret' debugging facilities in Mac OS X, including environment variables, preferences, routines callable from GDB, special files, and so on. If you're developing for Mac OS X, you should look through this list to see if you're missing out on something that will make your life easier.
Debugging memory allocators, debugging information printing functions for use in GDB, debug versions of system libraries, debugging Apple Events, AppKit view outlines, and loads of other helpful stuff for debugging and development in OS X.
