XPostFacto

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.[1]

Functions

XPostFacto allowed Darwin, OS X, and OS X Server 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.[2] 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.[3][4]

XPostFacto is available for free, but the company offered support for either $10 or $25.[5][3]

Supported models

XPostFacto 4.0 works with pre-G3 Macintosh models.[2] Beige box Power Macs as old as upgraded 7300-era machines are supported.[5] Limited support was also available for Performa 6400 and 6500 models.[6]

Reception

Engadget gave XPostFacto a negative review for its slowness, stating it "runs like a limp turtle on our old iMac G3."[7]
