Disable the Crash Reporter Dialog in Mac OS X
If you’re a developer (or anyone else) you may quickly get fed up with the Crash Reporter Dialogue box that pops up when an app melts down and crashes in Mac OS X. You can disable the Crash Reporter dialog box by launching the Terminal and entering the following command:
defaults write com.apple.CrashReporter DialogType none
and you can show the Crash Reporter again by entering the following at the command line:
defaults write com.apple.CrashReporter DialogType crashreport
It’s generally best to leave this kind of thing set to the default settings, and sending in crash reports actually helps Apple debug and improve software, but if you have a compelling reason to disable it, now you know how to.
