Newer versions of PAF for DOS can be run under OS X using DOSBox, and Windows versions can be run under OS using CrossOver or Wine. PAF 2.3 for Mac was also known as MacPAR and Family Records. There hasn’t been a new official version available for the Mac (Macintosh) platform for over 20 years, and the last version for Mac only runs under the “Classic” Mac environment (up through OS 9).
I still get questions about it here in 2015.
Personal Ancestral File, aka PAF, was a very popular genealogy application for many years, whose development dates back to the 1980s, and for some genealogists, it was the only program they would use.
