Read the "Migrating an App to a Sandbox" section of the App Sandbox Design Guide: http://developer.apple.com/library/mac/#documentation/Security/Conceptual/AppSandboxDesignGuide/MigratingALegacyApp/MigratingALegacyApp.html#//apple_ref/doc/uid/TP40011183-CH6-SW8 > > 2.

This is prohibited under sandboxing. Read "Accessing Preferences of Other Apps" in the App Sandbox Design Guide: http://developer.apple.com/library/mac/documentation/Security/Conceptual/AppSandboxDesignGuide/DesigningYourSandbox/DesigningYourSandbox.html#//apple_ref/doc/uid/TP40011183-CH4-SW12 > All of these issues are show stoppers for me being able to use the sandbox, > and with Apple declaring that all apps submitted to the app store must be > sandboxed, this becomes a major issue.
