I don't think OS X applications have a meaningful concept of "current
directory." And even if they have, is the current directory local to
the document or the application? In any case it doesn't work
regardless whether I start Skim from the input directory. Probably it
uses the directory of the .synctex.gz file as starting point for
relative paths, and I think this is entirely fine because the SyncTeX
functionality should not depend on how the viewer was started. Since
the input directory doesn't seem to be stored in the synctex file, the
viewer has no possibility of finding the input files.

That is correct, but I think this would be a minor flaw because the
correct information will be restored as soon as the document is
recompiled. However, if relative paths are a requirement, they should
be either relative to the output directory or not used at all when the
output directory differs from the input directory.
