 > @barracuda156 I’m afraid I don’t have the means to submit a PR.

 I think anyone can do it (merging gonna require an approval, but
 submitting is open to everyone), but if you share I suggested fix, I can
 open a PR from my end. (I cannot test on 10.9 though, and cannot test on
 any Intel at the moment.)
