Other World Computing (OWC) on Thursday released XPostFacto 4.0, the latest version of the companyis utility that helps owners of older, unsupported Macs run Mac OS X. This update adds support for Mac OS X v10.4 "Tiger," enabling owners of Macs no longer supported by Apple -- the original iMac and iBook, Beige G3s and Wall Street and Lombard PowerBooks -- to run the latest operating system.
The utility even works with machines that Apple never included in its OS X support, such as the Power Mac 7300 to 9600 series, which do require a G3 or G4 upgrade to run v10.3 or higher. XPostFacto can install Mac OS X v10.2 through v10.4 and avoids the misapplication of the 8GB limit placed on older machines by the OS X Intsaller.
XPostFactor is freeware, although OWC does ask for a US$25 donation to support its continued development. Registered users also get access to OWCis OS X tech forum as well as free notifications of XPostFacto updates.
