FSCatalogSearch is part of the deprecated Carbon File Manager API. The Carbon File Manager API exposes file IDs and directory IDs as 32-bit values and so FSCatalogSearch will never be supported on APFS (which use 64-bit file IDs and directory IDs).
In 10.13: • PBCatSearch on APFS volumes will return paramErr. • FSCatalogSearch on APFS volumes will return errFSOperationNotSupported. • PBGetVolParms and FSGetVolumeParms on APFS volumes will return with vMAttrib.bHasCatSearch and vMExtendedAttributes.bSupportsFSCatalogSearch clear. (There was a bug that made it look like PBCatSearch and FSCatalogSearch were supported on APFS.) > On Jul 6, 2017, at 7:49 AM, Thomas Tempelmann <tempelm...@gmail.com> wrote: > > Two things: > > 1. > A long while ago the APFS team at Apple asked for input on what's needed - I > then asked for fast catalog search support, in the ways of the searchfs BSD > function.
