I know it is not really possible and with high likelihood it is just a "bug" in the hitup.org software, but nonetheless, there seems to be a user (the third one) with OS X 10.9.6
There's another person with 10.9.6... I would find it weird to have it updated now, but I think some system did receive some updates even after other major OS were released.
