Check out this website:

This is a a very nice HP-15C simulator (Windows, Linux, Mac) that includes a USB interface to SwissMicro's DM15L, allowing copying of programs, etc. It may be just what you are looking for.
The interface with the DM15L need a complicate configuration on the Mac ? (it is a little bit difficult for me to do theses configuration: I always miss something ... that explain my comment about the DM41L firmware that I did not upgrade).
Have a good day
Olivier
