Are there any programs that run on OS X (and not just Windows) that can take a knot diagram as graphical input and convert it to a PD / Gauss code or braid? This is related to this question.
For comparison: On Windows, one can use LinKnot inside the Mathematica KnotTheory' package to convert a hand-drawn knot diagram into a Gauss code.
SnapPy has a link editor that can give you the DT code: https://www.math.uic.edu/t3m/SnapPy/plink.html
