Share user defaults between users

I'm using user defaults to store my app data.

I have some global data that is relevant for all users on the same machine.

How can I share this data between them?

NSUserDefaults' initWithSuiteName did not work.

The only workaround I found it to write to a hidden file in the root folder, but that is too visible to the users.

You can use the /Users/Shared directory like iTunes & the App Store.

You could use CFPreferences APIs instead of NSUserDefaults, passing kCFPreferencesAnyUser as the user name parameter. However, setting defaults for all users requires admin privileges.

The closest you could do is to make all of the users be members of a single group, then make a group writable file with the shared data. It could be a plist and it could even be accessed via the defaults API, assuming you don't need multiple simultaneous write access.
