Oh &

"Mac OS X 10.4.8 will now run on any generic x86-based PC. Well, almost. Kernel
coder Semthex has posted what he claims is an entirely legal release of the Mac
operating system's foundation layer. The only snag: you can't boot into the
familiar GUI.

To date, the version of Mac OS X for x86 processors has relied on kernel
add-ons to anchor the software to Apple's own hardware through the machines'
Trusted Platform Module (TPM). Much of the core code is independent of it,
however, and available for access to all and sundry via Apple's own source code
licence."

OpenSource strikes back
