Mac OS X
In Mac OS X there is a standard crash reporter in /System/Library/CoreServices/Crash Reporter.app. Crash Reporter.app sends the Unix crash logs to Apple Computer for their engineers to look at. The top text field of the window has the crash log, while the bottom field is for user comments. Users may also copy and paste the log in their email client to send to the application vendor for them to use. Crash Reporter.app has 3 main modes: display nothing on crash, display "Application has crashed" dialog box or display Crash Report window.
