Plenty on-line bitmap to vector converters. There might be one that does a center-line conversion, I-do-not-know.
On the other hand Mac might have some great vector application tucked away.
You could try the latest 0.92.2 Inkscape which should have a center line option (Inkscape menu Filters -> Extensions -> Images -> Center-Line Trace)
https://inkscape.org/en/release/0.92.2/
As I understand it this might need an old command line application Autotrace to function. It looks like you get it here. http://macappstore.org/autotrace/
If Inkscape + AutoTrace does not work then worth trying Autotrace on its own.
My linux installation requires .bmp format with compatibility option turned on.
A typical line drawing from the internet probably needs cleaning up - jpeg artefacts for example. Some editing as well. Snoopys nose or eye as solid black does not work - no line to trace. Here is the command in a terminal, the original .bmp image and the vector single line SVG.

Depending on the complexity of the image, not impossible to use Gimp and trace over with the path tool. Just takes a bit of care, time and practice.
