Arguably, here's what should (have) happen(ed): 1. March 2012, OS X 10.7.3 introduces security-scoped bookmarks. You update your app to start generating them 2. June 2012, sandboxing deadline for App Store. You update your app to be sandboxed at some point around then or later. Most documents already use security-scoped bookmarks. For those that don't, prompt using open panel By leaving it until now to worry about security-scoped bookmarks, you've placed yourself at a bit of a disadvantage. How are you currently storing references to external files? Bookmarks, aliases or raw paths? Ideally you'd already be storing bookmark data, so it's no change to the document format to add in security-scoped info too. Similarly, bookmark resolution can always fail because the file has been deleted or moved somewhere the system doesn't recognise. If this happens you ought to provide some sort of alert to the user, including an open panel to locate the file or its replacement. Upgrading to a security-scoped bookmark can follow the same pattern. Of course, with a large quantity of files that could become a big pain. In which case your best bet is to use the open panel to locate the *folder* containing a number of the files. That grants you access to all the other files within the folder. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
