That won’t work. kCFURLBookmarkCreationPreferFileIDResolutionMask was never
implemented and the option didn’t make sense anyway (if anything, it should
have been a resolution option, not a creation option).
// deprecated
kCFURLBookmarkCreationPreferFileIDResolutionMask CF_ENUM_DEPRECATED(10_6,
10_9, 4_0, 7_0, "kCFURLBookmarkCreationPreferFileIDResolutionMask does nothing
and has no effect on bookmark resolution" ) = ( 1UL << 8 ),
