PearPC is an architecture-independent PowerPC platform emulator capable of running most PowerPC operating systems..."
-Wikipedia
What does this mean?...
PearPC is an emulator (a program that can run a guest operating system on another [host] operating system) that is able to implement the necessary hardware to run most PowerPC based operating systems on a computer with a x86 processor. Simplified, this means that possible to use PowerPC to run PowerPC Mac os X (and many other operating systems for the PowerPC architecture such as various distributions of Linux) on most PCs. This is currently the only know way to do this.
Unfortunately PearPC does have some limitations... Sound is still in an early development stage and therefore isn't stable and may not function properly on most PCs. In addition, USB is not supported, although PearPC does virtualize USB ports, tricking the guest operating system into thinking that USB is supported, but just not in use.
It is unclear whether running Mac os X on PearPC is really illegal, as Mac os X isn't modified through the process. Since Apple hasn't ever written the developers of PearPC, it continues to be thought as a safe solution. If there ever was a legal way to run Mac os X on a Pc, PearPC would be the way.

Now that Mac os X has switched to the x86 architecture, it is now possible to even run Mac os X natively (without the use of an emulator) on a PC. This is a cool idea, although it is illegal, as tweaking was necessary to do this.
You see, Apple doesn't want their operating system to be able to run on non-apple hardware, as they profit more from their physical computers than their software. In order to make it so that their operating system, Mac os X would only work on a real Mac, the TPM chip was introduced. TPM stands for Trusted Platform Module. This chip is existent in all of the new Intel Macs. The TPM chip basically is required by Mac os X in order to run. Without the TPM chip, Mac os X will not run. Since the TPM chip is only produced and found within Macs, Mac os X shouldn't be able to run on a PC. Due to illegal duplications of cracked Mac os X developer install DVDs that have been floating around, people have successfully run Mac os X on their PCs (without the use of PearPC). The cracked version enables use of Mac os X for Intel on a normal PC, as it removes the requirement of the TPM chip that is not found within a PC. This cracked version is often called osX86 or the "deadmoo image" (in reference to the osX86 installation disk image).
There is absolutely no doubt that OSX86 is illegal as it violates copyright, and the Eula (http://www.apple.com/legal/), which states that Mac os X may only be installed and used "on a single Apple-labeled computer at a time." Apple is well aware of all of this and as their enforcement of their copyright hasn't completely taken care of this situation, they have taken action against distributors and knowledge of this by shutting down involved web sites that either offered the copy itself, or contained information regarding the use and/or installation of the illegal copy. In addition to their effort to abolish this illegal activity, Apple has tried to keep the public's awareness of this tuned down. Although there have been many disputes against osX86, it continues to exist thought the web, as people who have already downloaded it have redistributed their copy.
As that copy of Mac os X is for Intel, it may not be able to run on PearPC. Instead the cracked Mac os X copy is commonly used by many people natively on their PC, or though the use of emulators such as VMWare. VMWare, along with many other emulators don't emulate the processor; instead the physical processor is used. As Mac os X for Intel wasn't intended by Apple to use on PCs, not all PCs contain supported hardware, and therefore not all PCs can run Mac os X for Intel. Currently, only processors that support SSE2 or SSE3 are able to run Mac os X for Intel successfully. Just because a PC's processor is supported means that it will run and function like a normal Mac. Many PCs use a different video and sound card than Mac os X supports. Processors that support SSE2 only (and not SSE3) are unable to run applications originally built for PowerPC. With SSE3 both applications originally built for PowerPC and applications built to be compatible with the new Intel chip should work.
All-in-all it seems that Mac os X may not only be limited to its use on a Mac.

From the very fist glance searchchips.com might seem like another advertising company attempting to suck up money from your wallet, however in more depth this site may not be giving an empty promise after all. Searchchips.com is a search engine that rewards its users with free merchandise such as the all very well known iPod. Many people question as whether this is genuine. Is it too good to be true? Take a look at this site... is it just another phony, or the real thing...[ 113 comments ] ( 12440 views ) | permalink | related link |
