Update :  그동안 수 많은 사용자들이 macOS를 일반PC에 설치하여 사용하고 있다.  이 글에서는 전체적인 개념 정리를 위한 것일 뿐 안정적이고 전문적으로 사용하려는 사용자들을 위한 글은 아니다.  일반적인 개념보다는 조금 더 전문적이고 안정적인 시스템을 원한다면 아래 카페의 글들에서 다양한 견적들과 안정적으로 사용할 수 있는 시스템 스펙에 대한 정보를 구할 수 있을 것이다.

We were dreaming about it, and Netkas did. Originating from the Hackintosh projects, those "extensions" can be installed on most PC version of Radeon without requiring to flash the BIOS of those cards. How does it work? In summary, those extensions include part of the EFI code required for the card to be recognized by the Mac and to have them active in Mac OS X. Hereafter are results obtained after installing a Radeon HD 4890 PC version in a Mac Pro 2008:

Hereafter is the procedure to get to this point:

• Install Radeon HD 48x0 drivers shipping with Mac Pro 2009: http://www.sendspace.com/file/gvsi12
• Install extensions allowing recognition of those PC version cards: http://rapidshare.de/files/46982841/ATI_Init.pkg.html
• Install patched extension to activate 3D acceleration (only for cards not recognized by the system as HD 4890): http://rapidshare.de/files/46893369/accel.tar.bz2.html You can also for those cards use the application kexthelper.

This procedure works with most Radeon: HD 4870, 4870X2 (recognized as 2 HD 4870), HD 3870, HD 4890, ... On our card, the first DVI works perfectly as a DVI Dual Link port, while the second one is only a single link. Beside this detail, everything is just working fine. Unlike with the Mac Edition card, such extension-activated card is becoming only active during the loading of Mac OS X and all components, and not immediately after the boot. This could be a problem is you want to boot from another partition or as a single users, however, it is so much easier than flashing the original BIOS of the card, that it should be considered by most users.

• RBE is a handy tool to modify several interesting parameters in ATI BIOS files. It focuses on fan and clock settings as these are the most important things to most users. BIOS modification is an alternative to using memory resident tweaking utilities such as RivaTuner, ATI Tray Tools or ATITool.
• But RBE can do more than that: It will balance the BIOS file's checksum, lets you modify the Overdrive settings, enables superior PowerPlay functionality for some video cards, contains a CCC profile editor for hidden features of the CCC and much more.

• Can display and change a lot of information strings inside the BIOS file, including Device ID and vendor ID.
• Accesses every PowerPlay state and can change GPU clocks, RAM clocks and voltage for each of them seperately.
• Displays the PowerPlay structure of the BIOS.
• Also displays the voltages the card can make use of.
• Can graphically display and modify four different fan controllers in a very comfortable way and automatically figures out which controller is used for a particular BIOS.
• RBE modifies the Overdrive signature of a BIOS to enable a higher overclocking limit. Signatures can also be extracted and saved to a file.
• Will make the annoying spin up bug some cards have vanish.
• Enables superior PowerPlay.
• Contains a profile editor for accessing hidden CCC panel features.
• Acquires and flashes BIOSes all from within RBE using the built-in WinFlash interface.
