However, the newer frameworks relied on the newer kernels and this led to users of 10.4.8 encountering many problems.
Apple also started making more use of SSE3 instructions on their hardware making it even more difficult for users with CPUs supporting only SSE2 (such as older Pentium 4s) to get a fully compatible system running.
These machines used Extensible Firmware Interface (EFI) platform firmware instead of the older style BIOS found on most x86 motherboards at the time.
On February 14, 2006, an initial "hack" of and again patches were released within two weeks that allowed users to install most of this update on non-Apple computers, although this did not include the updated kernel in 10.4.6.
Within hours of Leopard's release, an AMD/Intel SSE2/3 Kernel Patcher was created that removed the HPET requirement from an original untouched mach_kernel file, a core component of the Mac OS.
When "Snow Leopard" was released, Russian hacker netkas created a version of Chameleon that can boot Mac OS X v10.6.
Most of these kernels aim to allow users to run Mavericks on AMD and older Intel CPUs, which lack certain instruction sets of the latest Intel CPUs.Since v10.6.2 Nawcom, Qoopz, and Andy Vandijck have been working on Legacy kernel for unsupported CPUs.When Apple released the Developer Preview 1, a Russian Hackintosh developer usr-sse2 was the first who created a method to install Lion.Some other popular distros are i ATKOS, Kalyway, i PC, i Deneb, and Niresh.Distros have fallen out of favour as the OSx86 community grew, as new bootloaders were developed that made it possible to use actual copies of the OS X Installer.They continue to be refined and updated builds released, not just to maintain compatibility with Apple releases but an ever-increasing number of third-party components.The OSx86 community has been quick to make the necessary modifications to enable Apple's latest releases to run on non-Apple hardware.However, all of these compilations rely on the work of kernel hackers made by Lorem (build 9A466), Syntheti X (builds 9A499, 9A527 and 9A559), To H (builds 9A581, 9B13 and 9B18) and more recently a group calling themselves Stage XNU (now called Voodoo) (Darwin 9.4.0).Their contributions trickled down into the various Mac OSx86 installers, readily available on the Internet.The method consists of deploying Mac OS X v10.7 image on a flash drive, and booting from it via XPC UEFI Bootloader (See DUET below).After some changes were made to the Chameleon source code, booting of Lion was possible with an updated version of Chameleon.
