Jason, the PAF 2.31 for Macintosh is still available on the Family Search website. It can not be downloaded, but can be ordered for USD10 (diskette).
There are very few genealogical programs for the Macintosh. One of the best, I believe, is Reunion, but I can't see anywhere on their site that it has provision for Temple Ordinances, which you are seeking. Read about it at: http://www.leisterpro.com/index.shtmlhttp://www.leisterpro.com/index.shtml
This index will give you a list of other genealogical programs for the Macintosh. Most, excluding Reunion, are more than five years old, indicating the lack of development in this area: ftp://ftp.cac.psu.edu/pub/genealogy/mac/INDEX.html
Perhaps, as a workaround, you could create a GEDCOM of your data in your current program, and import that into PAF at a nearby FHC. Then create your Temple Ordinances there.
