I would be amazed if the automatic download currency conversion worked on a Mac. The manual download conversion might work. If not, let me know and I'll Email you a URL to use to get the needed table. Let me know the base currency you want to use, also.

BTW, I have uploaded a plain ZIP file here for those users who want to save about 60K in the download and who already have an unZIPper or Stuffit on the Mac. As a former Mac user and fan of Ray Lau's initial work, I'll do whatever I can to help out those remaining Mac users.
