I am not an expert and I don't have a Mac but I guess your best chance is to install wine for Mac OS (https://wiki.winehq.org/MacOSX) and try to run the Windows version of netpanzer with that, as this trick works pretty well in Linux.
It would be nice then to let us know if it worked.
I am no expert but wine didn't seem to work for me. However, I will keep on trying modifying it and reply if I find a solution. There is a nice guide for other good mac-solutions that I use sometimes here.
