Usually, when an app crashes in OS X, you get a pop up warning from Crash Reporter in the middle of the screen. That's not always the best place for it, and if you'd prefer to have the warning in your Notification Center, Defaults-Write shows you how. To swap the crash report screen pop up over to the Notification Center, you'll need to use a Terminal command. Open up Terminal (Applications > Utilities) and type this in:
defaults write com.apple.CrashReporter UseUNC 1
When you're done, go ahead and reboot. Now, your crash reports will appear as a notification. To change it back, just swap out the
1 for a
0 at the end of the command and run it again.
