Apple's transition to Intel processors
The use of the x86 architecture allows Windows to run natively on Apple hardware, and opens the possibility of using the Wine package to run Windows executables directly. Some [ who? Others say that it could be a boon to switchers , since they would not have to leave their Windows applications behind while trying out Mac OS X.
Intel was seen among the Mac community as a purveyor of hot-running chips especially the Pentium 4. Apple themselves mocked the Pentium range in their "Toasted Bunnies " advertisements of the late s. However, the Pentium M chips, which were designed for laptop use, run much cooler than the Pentium 4. Apple claimed the then-new Intel Core chips, which are based on the Pentium M microarchitecture, would have dramatically better performance per watt than the PowerPC G4 and G5.
Finally, the relative quality of the x86 architecture has been discussed.

Critics of the switch say that x86 was a poor choice because of its lack of hardware registers compared to the PowerPC, and the lack of AltiVec also known as Velocity Engine. Proponents have responded by saying that the x86 architecture has evolved greatly since the original was introduced, and that CPUs in general have combined RISC and CISC philosophies in their internal designs for some time, making the distinction obsolete.
They also point out that improved SSE could equal AltiVec , and that most programmers rarely deal with x86's peculiarities because the compiler does the work. The PowerPC G5 was a bit design, although very few applications made use of the increased address space. In contrast the original Core Solo and Core Duo chips were bit. On August 7, , Apple released the Mac Pro and Intel-based Xserve , introducing Intel 64 Intel's implementation of x architecture into the lineup through the use of the Xeon processor. As of August 7, , all other computers in Apple's product line have been updated with the bit Core 2 Duo.
While the current benchmarks comparing Core Duo to Core 2 Duo processors show very little difference when running in 32 bit, the 64 bit edge has become more of an issue with the release of Mac OS X v Java applications that do not rely on Java Native Interface , some Dashboard Widgets , and scripts that execute inside an interpreter all work immediately on both processors and are immune to changes.
Rosetta is an instruction translator comparable to the 68k emulator that allows PowerPC Macintoshes to run pre-PowerPC code, rather than a virtual system like Classic ; it does not require a second operating system to be loaded as a subsystem before the application can work.
AltiVec itself has been encapsulated since Mac OS Cocoa applications can be ported simply by recompiling them and checking for endianness problems.
Carbon applications required some additional tuning, but not of the complexity of the transition from Mac OS 9. Applications written using Metrowerks CodeWarrior suite had to be modified; those that use PowerPlant required further code changes, described by Apple and Metrowerks. Classic is not supported on the x86 architecture. From Wikipedia, the free encyclopedia. For details on the architecture of Intel-based Apple computers, see Apple—Intel architecture.

We'll be discussing the process of building a hackintosh on a broad level, as it applies to most hardware. As a result, this guide will not always be able to tell you the exact boxes to tick and choices to make, but it will teach you how to figure that out for yourself. We'll hold your hand as tightly as possible through as much of the process as we can, but there will be some decisions you'll have to make on your own.
PC vs. Mac: Which Computer Is Right For You - Intel
It can be a little scary sometimes, but that's part of the fun. In summary, this always up-to-date guide will explain how to pick the right hardware for a great hackintosh and walk you through the standard OS X installation process, but it will also require you to be diligent and informed in regards to the variables in your specific build. Picking out hardware and building a computer is often the most daunting part of this process. If you've never done it before, it can often feel like putting together puzzle where many of the pieces seem interchangeable but truly are not. That said, we have plenty of resources to help you demystify the purchasing and building process so you're feeling confident.
When Apple builds their official Macs, their parts are not that different from the parts we can buy online when we build our own PCs. In fact, they're often the same. Additionally, third-party manufacturers will create hardware for Apple's Mac Pro computers to add additional options to the mix.
This means that Apple, or the third parties, need to create software drivers for Mac OS X in order for the hardware to work. This means that virtually any hardware with these drivers is going to be hardware you can use in your hackintosh build. Additionally, the talented people on the internet have developed their own open source drivers for non-Mac hardware in order to provide additional options for your hackintosh.
While all of these efforts only span a small percentage of the available hardware on the market, it still provides you with a lot of great choices. Many motherboards, graphics cards, and processors are compatible thanks to these combined efforts. The next question is, how do you know what is and isn't compatible? Like we've already discussed, if Apple has used the part before, that's generally a good sign that you can use it, too.
That said, you always want to double-check when you're putting your hardware list together. To help you out, we've created a hackintosh hardware buyer's guide so you can figure out what will and will not work. Follow that guide when choosing your hardware and you should be good to go. You can also reference our Hack Pro and Hack Mini builds, or just use the sample build provided at the end of this section. Once you have your hardware you're going to need to assemble it into a working computer. We have an entire night school course on computer building , but this specific lesson will walk you through how to build your first computer.
Follow it diligently, read your motherboard and case manuals closely , and you should have a functional machine in no time. With the resources we've discussed, you should be all set to build your hackintosh. Before we move on, however, let's take a look at a sample build so you can get an idea of what a basic hardware shopping list looks like. This is an actual hackintosh we've built, based on hardware suggested by tonymacx Here's the parts list:.
You'll find lots of builds like this on tonymacx86's blog , so you can build those exact machines or use them as starting points to create your own build. However you want to go about it, be sure to read our a hackintosh hardware buyer's guide if you want help with selecting your parts. By this point you should have purchased your parts, built your computer, and turned it on to make sure everything is functioning. If all systems are go, it's time to move on to the installation process. Installing Mac OS X on hackintosh hardware involves a bit more than just popping in a DVD, choosing a boot volume, and clicking a button.
You'll have to do all of that, too, but there's a bit of prep work involved.
Let's get started. When you turn your machine on, it should display its BIOS welcome screen. This is generally an image with the name of your motherboard and indicators for a few keys you can press to edit your BIOS. This is almost always a function key like F12 or the delete key, but reference your BIOS image to be sure.
Click the image to the left to see an example. The BIOS settings for every motherboard is going to be somewhat similar but never exactly the same. For that reason we can't tell you, command-by-command, where to go to find and make certain adjustments. That said, we can tell you what to look for. Here are the settings you will need to adjust or at least verify in your BIOS to make your hardware hackintosh-friendly:. Once you've made these changes, you'll need to save them.
In most cases you'll only need to press the escape key a few times to get back to the main screen, and then F10 to save and exit. Your BIOS settings page will tell you which keys save, exit, and so on, so you should have no trouble figuring out the right keys to press.
