Where are core dumps written on Mac?

On Mac OS X, if I send SIGQUIT to my C program, it terminates, but there is no core dump file.

Do you have to manually enable core dumps on Mac OS X (how?), or are they written to somewhere else instead of the working directory?

It seems they are suppressed by default. Running

$ ulimit -c unlimited

Will enable core dumps for the current terminal, and it will be placed in /cores as core.PID. When you open a new session, it will be set to the default value again.

by default, specific directories in mac osx are hidden. you might want to enable this feature in the terminal and then the core dump should be visible within the directory /cores.
