I don’t really have time to look at the current fts implementation, but… it has
several options that effect performance (in particular, the FTS_NOCHDIR,
FTS_NOSTAT, FTS_NOSTAT_TYPE, and FTS_XDEV options). If you are trying to
compare fts to CFURLEnumerator (for example), use FTS_NOCHDIR and

Here's something that is kind of related that I ran into recently.
If you have code that is checking the ownership and permissions of a file
system object and attempting to correct the ownership and permissions if it is
wrong, don't bother if the MNT_IGNORE_OWNERSHIP mount flag is set --

When a user drags a file system volume out the Devices sidebar list, the
Visibility is set to NeverVisible for that device in the list (as you can see
below). The Bookmark is a URL bookmark object (serialized) used to determine
which file system volume should be hidden
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

Q_MOUNT kernel event and that's what causes the kNotifyVFSMount BSD
notification to be sent. At that time, file systems must be ready to respond to
requests correctly. If they don't, they have a bug.

As -[NSURL getResourceValue:forKey:error:] is documented, "If this method
returns YES and the value is populated with nil, it means that the resource
property is not available for the specified resource, and that no errors
occurred when determining that the resource property was unavailable."

Have you looked at an APFS file system in the WWDV seed? Have you watched the
WWDC presentation? Those would answer a lot of your questions.

Apple doesn't support trash directories (or temporary item directories) on
network volumes and hasn't for quite a while because there is no good mechanism
to clean up trash on network volumes (i.e., if a user mounts a network volume,
moves files to the trash, unmounts the network volume, and
