PolyFactors 1.0 for Mac was available as a free download on our application library. The actual developer of this free Mac application is Bob Delaney's Science Software. The application lies within Education Tools, more precisely General.
From the developer:
PolyFactors factors univariate polynomials over the integers.
PolyFactors uses the ZZX polynomial type and the ZZXFactoring routines from Victor Shoup's NTL (http://www.shoup.net/ntl/). He deserves most of the credit. PolyFactors just provides a GUI for input and output.
PolyFactors is a Universal Cocoa application.
