问题
Does anyone know how to open the Local Items keychain (new in Mavericks) with SecKeychainOpen? There are certain entries in that keychain that I'd like to be able to ask the user permission to access using SecKeychainFindInternetPassword.
e.g. for the System keychain you call SecKeychainOpen ("/Library/Keychains/System.keychain",&keychainRef).
