Mac OS X86 adalah sebuah sistem operasi yang merupakan hasil hacking dengan dasar Mac OS X versi Intel. Tujuannya ialah menghadirkan sistem operasi Mac OS X kepada pengguna PC Intel.

Mac OS is a completely capable OS that provides functionality and services similar to Windows or Linux OS. Some of the code base and features of Lisa OS have been incorporated in Mac OS. Mac OS is designed to operate on Apple manufactured PCs and by default, does not support x86 architecture.

Given that choice, the Apple Silicon M1 (and M2) chip is an AArch64 architecture. AArch64 is another name for ARM64, so it is an ARM architecture. The AMD64 architecture is what is also known as x86_64, x64 or even Intel 64-bit architecture. This is what you would typically see in slightly older Macs introduced before Apple Silicon.

Essentially, ARM (which the M1, iPhone, iPad, and Apple Watch chips use) and x86 (used by Intel) are two different kinds of processor architectures. If that sounds complicated, it’s because it is – so don’t worry! Here’s a simple way of thinking about it: The processor is like your computer’s engine.
