How to Make Crash Reporter Appear as a Notification in Mac OS
Advanced Mac users who are either in development or another field which experiences frequent app crashing may find the persistent Crash Reporter windows with the ‘App quit unexpectedly’ message to be a nuisance, interfering with their workflow in Mac OS X. While one longstanding option is to disable the Crash Reporter dialog completely in MacOS X, perhaps a better approach is to send those crash reporting dialog boxes into notification center instead.
To be clear, this does not disable the Crash Reporter dialog windows, and it has no impact on crash logs themselves, it simply transforms the crash alert into a Notification within the Notification Center of Mac OS X. If you click on the crash report notification, the regular Mac crash report screen will open as usual.
Enable Crash Reporting as Notifications in Mac OS X
Open the Terminal and enter the following defaults write command string:
defaults write com.apple.CrashReporter UseUNC 1
Hit return and that should be all there is to it, the next time an app crashes it will appear as a notification rather than a dialog window.
You can test it out yourself by intentionally crashing and beach balling an app or using force quit on a busy application in the ‘not responding’ state.
Return Crash Report to the Default Dialog Window Option in Mac OS X
To disable the crash reporting as a notification feature and return to the default crash reporter dialog box, use the following defaults string instead:
defaults write com.apple.CrashReporter UseUNC 0
Now if you crash an app it will open the typical alert dialog on the Mac.
This should work with any modern version of Mac OS , a big thanks to Franz D. for sending in this tip!
