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. 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. What Semthex has claimed to do is produce code that essentially bypasses the TPM stuff yet stays within the Apple licence.
