In some cases it is useful to know why an application exits (crashes). In Mac OS X, it is possible to activate a log that allows you to see the activity before the crash. To enable this log:

Open a terminal session and go to the directory / etc in this directory hostconfig open the file with an editor like vi, emacs or pico. At the end of the document add the line:

CRASHREPORTER=-YES-

After adding this line save the file and reboot so that the log is active.

Now that the log is activated during the crash of an application, a window will open.

The logs will be written to / var / log / crashreporter.log.
