I was exploring all of the above possibilities.  I've been using Ciderpress and HFVExplorer on my PC.  I got stymied at the step where I put the IIc formatted disk into my mac. I guess I should look into getting the prodos file extensions installed or getting a serial cable.

Macs certainly can be mysteriously confusing creatures!  Most of my 1980's vintage computer experience is with ancient DOS computers and ti99/4a's (which is surprisingly straightforward for a 35-year old system)
