I just double-checked, and it works fine for me in a simple test:
git init
mkdir subdir
for i in 1 2 3 4 5; do
echo $i >base-$i
echo $i >subdir/sub-$i
git add .
git commit -m $i
done
git filter-branch --subdirectory-filter subdir -- --all
That's on:
$ sw_vers
ProductName: Mac OS X
ProductVersion: 10.9.5
BuildVersion: 13F34
However, I notice the error message you show has non-ascii dashes when
it prints "--subdirectory-filter". That matches what you said below:

Are you sure that you are invoking filter-branch with regular ascii
dashes, and not Unicode "minus-sign" (U+2212)?
I seem to recall this coming up once before related to OS X, but I can't
seem to find it in the archive. And I don't recall if it was related to
the terminal, a keyboard setting, or something else.
