The short answer to do exactly what you ask is 'No'. You could use a Mac OS progamme and point it at your folder containing the photos but the chances are it will not interpret your FTM GED file accurately. Different programmes interpret the GED standard in slightly different ways. Your best bet is to run FTM on the Mac using a virtualisation programme such as V-Box, which is free and works a treat for Windows applications if you really have to use them.
