Other World Computing today announced that it will demonstrate the beta version of XPostFacto 3.0 in its booth (#2323) at Macworld Expo in San Francisco. XPostFacto 3.0 enables users of older Macs to boot Mac OS X 10.x from an external FireWire drive using a FireWire PCI card. Other enhancements to version 3.0 include an updated interface and integrated support of the L2 and L3 cache on G3 and G4 CPUs, which the press release says will significantly accelerate the installation process, as well as offer support for CD booting. XPostFacto 3.0 is expected to be available for free download from the OWC Web site in the first quarter of this year.
