According to InsanelyMac forum member [qbattersby] the EFiX USB dongle he just received doesn’t seem to live up to expectations. We covered the EFiX when it was announced back in June. It’s designed to let you install OSX unmodified on commodity hardware. While using a MSI G965M motherboard, instead of installing OSX [qbattersby] was greeted with a flashing cursor with no option to continue onward.
A quick glance at the EFiX hardware compatibility chart does not list the MSI G965M as a board verified to work with the dongle and could explain [qbattersby] results. To his defense, he does explain that he will be testing it on a supported motherboard along with a retail copy of Leopard in the future. Hopefully, he will be able to post back that it works and his experience with the installation of Leopard.
While the EFiX seems to be shipping in some countries, enthusiasts in the US will have to wait a bit longer till distribution channels can be worked out.
One thing is for sure, if you do plan on going the EFiX route, make sure that the hardware you plan on using is listed on their site.
