Mac OS X Reference Library Technical Note TN2123 states:
CrashReporter performs two useful
actions:
- When a program crashes, CrashReporter will record a crash log
(typically into
~/Library/Logs/CrashReporter/), and
inform the user by logging a message
to the system logging facility.
- In addition, if the program that crashed is running as a logged in GUI
user, CrashReporter will present the
user with a dialog asking them whether
they want to submit a bug report to
Apple (see Figure 1). If the user
clicks the Report button,
CrashReporter displays another dialog
that shows the details of the report
(see Figure 2) and allows them to
comment it before submission.
And not much further along, states:
In this technote I explain how to interpret crash logs that you have obtained from end users.
I believe this implies that the information is not automatically shared with the developer. The developer needs to "obtain" the crash logs from the end users' ~/Library/Logs/CrashReporter/ folder.
