XPostFacto 4.0 Adds Tiger to More Legacy Macs -- Other World Computing has released its latest version of XPostFacto, a tool designed to help owners of Macintosh models not supported by Apple for specific Mac OS X releases to install and use those operating system versions. The latest version adds support for Mac OS X 10.4 Tiger. XPostFacto 4.0 enables the installation of the stripped-down Darwin Unix base of Mac OS X, as well as Mac OS X (client version) and Mac OS X Server. It can install Mac OS X 10.2 through 10.4. The operating system must be purchased separately.

The company noted in a press release that this version handles computers as old as the Power Mac 7300, which shipped in 1997. Many computers that lost Apple's support with the Tiger release can accept a Tiger upgrade, although without Apple's testing, it's entirely possible that additional quirks and problems may appear. The software, developed by Ryan Rempel, is free for use, but the company suggests a $25 donation to help continue supporting the software's development. [GF]
