My guess is that it’s for one of two reasons: 1. Because this is a package, the UTI must be declared to conform to com.apple.package, not public.data. (According to https://developer.apple.com/library/mac/documentation/General/Reference/InfoPlistKeyReference/Introduction/Introduction.html <https://developer.apple.com/library/mac/documentation/General/Reference/InfoPlistKeyReference/Introduction/Introduction.html>, the “LMTypeIsPackage” key is ignored when a ”LSItemContentTypes” key is present. The list of sub-keys under ‘CFBundleDocumentTypes’, also says which other keys are ignored in this case, such as CFBundleTypeExtensions.) So, right extension, wrong structure, and LS couldn’t figure out what you meant. There’s a document somewhere that says how to configure a file type properly as a package and a non-package, but I can’t find it now. Non-packages should conform to public.content *and* public.data, IIRC, FWIW. 2. Because there’s an older, out of date app bundle on your system somewhere, and Launch Services is using that as its definitive source of information. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
