XPostFacto is an open source utility for Mac OS 9 that enables the installation of PowerPC versions of Mac OS X up to Mac OS X v10.4 (Tiger), and Darwin on some PowerPC-based Apple Macintosh systems that are not officially supported by Apple. It was released in 2002.
Functions
XPostFacto allowed Darwin, OS X, and OS X Server to run on unsupported Mac models. The OS X Installer would not run on machines without a G3, G4, G5, or Intel processor by default, but XPostFacto patched the installer to allow it to run. A Mac OS 9 partition must be booted first. XPostFacto then runs in Mac OS 9 using an installation CD to install a version of OS X.
XPostFacto is available for free, but the company offered support for either $10 or $25.
Reception
Engadget gave XPostFacto a negative review for its slowness, stating it "runs like a limp turtle on our old iMac G3."
