OSx86 Project reports the hacker already broken Apple security this summer on preliminary MacOS x86 edition, released a new patch, this time working with official MacOS 10.4.4 for Intel x86:
This is a preliminary release of my Patch Solution for the official Mac OS X on the Intel platform. Consider it a work-in-progess for now. Ultimately, it would allow you to run this Mac OS X release on a generic x86 computer (SSE2 required).
There’s still a lot of work to do, like support for SSE2-only CPUs, a proper installation procedure and a PPF patch. However, if you like to play around, this will get you started.
