AppSandboxDesignGuide.pdf says: ====================== Accessing Preferences of Other Apps Because App Sandbox directs path-finding APIs to the container for your app, reading or writing to the user’s preferences takes place within the container. Preferences for other sandboxed apps are inaccessible. Preferences for apps that are not sandboxed are placed in the ~/Library/Preferences directory, which is also inaccessible to your sandboxed app. If your app requires access to another app’s preferences in order to function—for example, if it requires access to the playlists that a user has defined for iTunes—let Apple know about your needs using the Apple bug re- porting system. In addition, be sure to follow the guidance regarding entitlements provided on the iTunes Connect website. With these provisos in mind, you can use a path-based temporary exception entitlement to gain programmatic access to the user’s ~/Library/Preferences folder. Use a read-only entitlement to avoid opening the user’s preferences to malicious exploitation. A POSIX function, such as getpwuid, can provide the file system path you need. For details on entitlements, see Entitlement Key Reference . ======================== I think that is your issue. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
