OS X is a popular operating system that has been installed on millions of PCs around the world. But there are still some challenges that can be faced when trying to install it on PCs. One of the biggest challenges is that many PC manufacturers do not include support for OS X, which can make it difficult to get started. Additionally, many PC manufacturers do not provide installation disks or manuals for OS X, which can make it difficult to get started.
Macs switched over to Intel processors years ago, but it is still a huge headache to run OS X on a PC. Read on as we explore the technical hurdles in installing Apple’s OS on a PC framework.
Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites.
The Question
SuperUser reader Braiam wants to know what the technical obstacles that prevent normal computer users from installing OS X on their PCs are:
Is it really as complicated as it seems ‘hardware-wise’ to run OS X on a PC, or are the differences between Mac computers and PCs smaller (and simpler) than most people believe?
Everyone knows that until recently, OS X (or Mac OS) could only be run on PowerPC-based Macs, but that changed when Apple started using Intel’s CPUs, and opened up the possibility of installing OS X on PCs. Again lets forget about legalese, I’m going for factual and technical references. After the switch, users started experimenting until it was possible to install and run OS X on a PC.
Does anyone know why OS X wouldn’t work on a normal person’s PC? Is it some piece of hardware that is custom made or tailored for OS X that only Mac computers have? Or is it just Apple making computer users’ lives difficult on a technical level?
The Answer
SuperUser contributor Journeyman Geek has the answer for us:
As you can see, while it may not be easy to get OS X up and running on a PC, it is doable. Interested in building your own Hackintosh PC? Then make sure to read through our terrific guides here:
Most Hackintosh install methods these days use variations of boot132, a bootloader that was provided when Apple was transitioning from PPC to Intel with some modifications. The original bootloader was open source, and built with some changes for Darwin. As an aside, there have been some attempts to repackage Darwin as an open source OS.
Apple supports a limited range of hardware you know will work. Otherwise, you’re going to have to scrounge up tested hardware or hack hardware into working. This is what makes running OS X on commodity hardware difficult. The SMC is relatively trivial to get around. Getting your unsupported sound chip (nothing like having your mic stuck at maximum volume on a laptop to ruin your day), video adaptor, and other hardware is the tricky part. If you have an AMD processor, for example, the stock kernel will take one look at it and panic like a mouse ran up its pants. In many cases, the solution ends up being building a new kernel, with patches off Darwin source (which is FOSS) and using that.
In short, the big problem isn’t the magic chip, it is OS X needing to play nice with the entire system.
