The Mormon church sell excellent genealogy software for Macs at a very low price. I have been using their Personal Ancestral Filer for about 9 years. I think it cost ten bucks or less. Check out their website http://www.familysearch.org/ or call the Mormon Church in Bicton, which has a very active genealogy research centre at the rear of the main building. Open to the general public.
On the website you will find free versions of PAF for PCs or Macs with PC emulation. In the for sale section you will find the specialise Mac software, which I see is still $10 or less. The may be available at Bicton, or able to be ordered there. The Mormons have similar research centres in other Australian states. Regards, Paul.
