Hi,
I’m having an issue where it appears that an Imported UTI for a certain file extension declared by one application is taking precedence over an Exported UTI for the same file extension declared by a second application. Everything I’ve read in the docs and elsewhere states that Exported UTIs take precedence over Imported UTIs, so I’m not sure what’s going on.
I’ve run `mdls [filename]` on an example file, and the kMDItemContentType and associated attributes that come back match those declared by the Imported UTI, not the Exported UTI. This causes problems because the two applications declare different UTI strings (kMDItemContentType) for the same file extension. Thus, when the application with the Exported UTI displays its Open File dialog, the files of the type in question are grayed out/unselectable because the dialog has been told (via [NSDocumentController runModalOpenPanel:forTypes:]) to choose files with the UTI string declared by the Exporting application, but Launch Services is assigning the other UTI string (from the Importing application) to those files.
Can anyone shed some light on what might be happening, or steps to troubleshoot/rectify the issue?
Thanks!
Matt
