Intel processors enabled MacOS users to natively run Windows (2006-2020).
From 2006 to 2020, a significant change occurred in the world of Mac computers. Apple, in a groundbreaking move, transitioned its entire Mac lineup from PowerPC processors to Intel x86 architecture. This shift paved the way for Mac computers to use Intel processors compatible with Windows operating systems, enabling native Windows compatibility on Mac computers through Boot Camp Assistant.
The Intel Era
During this period, Apple primarily used Intel processors from the Intel Core line (such as Core Duo, Core 2 Duo, and later Core i3, i5, i7, and Xeon processors for Mac Pro and Xserve). These processors, based on the x86 (and later x86-64) architecture, enabled the use of Boot Camp, Apple's utility that allows Mac users to install and run Microsoft Windows natively on their Intel Macs.
The PowerPC Era and Virtual PC
Before the Intel transition, Mac users running PowerPC Macs had to rely on Microsoft's Virtual PC emulation software to run Windows. However, this came with significant performance limitations. CPU-intensive tasks, graphics-heavy applications, and gaming performed poorly on Virtual PC due to performance constraints. Business applications, on the other hand, ran at acceptable speeds for basic tasks.
PowerPC processors also had significant limitations when running Windows, including slow application launch times and limited USB device compatibility. Moreover, no support for DirectX graphics acceleration was available with Virtual PC on PowerPC.
The Transition to Apple Silicon
In 2020, Apple began shifting to its own Apple Silicon ARM-based processors, culminating in the introduction of the M1 chip later that year. This transition meant that modern Apple Silicon Macs can run Windows, but are limited to ARM versions with some performance impact when running x86/x64 applications.
To overcome this limitation, virtualization solutions like Parallels Desktop, VMware Fusion, and CrossOver are available for Apple Silicon Macs. However, it's important to note that these solutions only support Windows through ARM-based virtualization, unlike the full-speed Windows performance with native DirectX acceleration and complete hardware compatibility provided by Boot Camp on Intel Macs.
In conclusion, the Intel x86 and x86-64 processors used by Apple between 2006 and 2020 were the processors that allowed Mac users to run Windows on their machines. The transition to Apple Silicon marks a new era for Mac computers, but it's clear that the Intel era played a crucial role in bringing Windows to the Mac.

- During the Intel era from 2006 to 2020, Apple users got the opportunity to install and run Microsoft Windows natively on their Intel Macs using Boot Camp, thanks to the Intel processors like Core Duo, Core 2 Duo, Core i3, i5, i7, and Xeon processors that enabled this compatibility.
- Prior to the Intel era, PowerPC Mac users resorted to Microsoft's Virtual PC emulation software to run Windows, but it came with limitations such as poor performance for CPU-intensive tasks, graphics-heavy applications, and gaming, and also faced issues with application launch times, USB device compatibility, and DirectX graphics acceleration support.
