OS X is an interesting case. The standard filesystem, as you note, is
HFS+ with journaling. Usually this is a danger sign for shredding as
the shred process doesn't know all the information it needs to do a
proper shredding job. However, Apple has shredding built-in to OSX, and
since both the shredder and the filesystem come from the same people,
it's at least possible that they did the necessary work to have this
shred properly (i.e. in a journal-sensitive way). Did they actually do
this? I have no idea, and would be curious to hear from someone who
does have a reference on this one way or the other. Apple tends to be
fairly stingy about this level of detail.
=================
test it!
fill a file with a few hundred copies of a random hash. as a control,
delete the file the normal way and try to find it on the disk (i'd expect
you can find it). repeat with a different hash, shred the file, and try
again to find it on the disk.
