Disable "The last time you opened *, it unexpectedly quit while reopening windows" dialog in OSX 10.8

Question

I managed to successfully silence the CrashReport dialog, but when my application crashes and I restart it, I get the annoying dialog as from Title. Is there a way to prevent it to appear, and just let the application run without interruption?

Answer 1

Try this to get rid of the reopening windows:

defaults write -app "Application Name" NSQuitAlwaysKeepsWindows -bool false

You may also disable it for every application by selecting this option in the preferences: "Close windows when quitting an application"

And for others reading this thread, to remove the CrashReport do this:

defaults write com.apple.CrashReporter DialogType none

Also note that in the source of this information they say:

For this to work one needs to check the box, open the program in question and immediately close it. On the next re-opening it will work without Resume.

You may also have to delete:

/Users/…/Library/Saved\ Application\ State/org.python.python.savedState/

Voila! I've just solved this problem by deleting all Unity-related files inside ~Library/Caches folder on my Mac!
