OSx86
OSx86 is a collaborative hacking project to run the Mac OS X computer operating system on non-Apple personal computers with x86 architecture processors. The effort started soon after the June 2005 Worldwide Developers Conference announcement that Apple would be transferring their personal computers from PowerPC to Intel microprocessors.
OSx86 is a portmanteau of OS X and x86. A computer built to run this type of Mac OS X is sometimes known as a Hackintosh, which is a recycled term originally denoting the modified Lisa 2/10 running Mac System.
Initial efforts revolved around leaked copies of the Development DVD that was released by Apple as part of the Developer Transition Kit that Apple made available to developers for $999. The first patches centered around circumventing the Trusted Platform Module (TPM) that was included on the motherboard of the Developer Transition Kits. The TPM was required by the Rosetta technology that allowed software compiled for the PowerPC architecture to run on Intel-based architecture. Removing this requirement allowed Mac OS X to be installed on non-Apple computers. Rosetta also required microprocessors that included SSE3 instructions. Patches were released to the community that emulated these instructions with SSE2 equivalents and allowed the installation on machines without SSE3 support (with a performance penalty).
In October 2005 Apple released a 10.4.3 update to developers that required NX bit microprocessor support. Patches were released to circumvent this.
