Apple’s upcoming Mac OS X 10.5.7 update may go beyond its usual complement of expected fixes and incorporate support for Intel’s new Nehalem hardware architecture as well as the ATI Radeon HD 4000 graphics chipsets.
According to netkas, a recent discovery located just five kernel extensions for the video cards and doesn’t appear to work perfectly in a bootleg installation for 10.5.6 meant for hacked Mac OS X installations. The retrofitted version doesn’t recognize DVI ports fully and doesn’t even recognize widescreen resolutions without third-party utilities to force the expanded screen area.
Even so, the extensions are enough to identify support for the Radeon HD 4850 and Radeon HD 4870 chipsets by name but also to enable Core Image and Quartz Extreme acceleration of the Mac OS X interface, which would require the direct involvement of AMD, Apple or both firms to work. They also support the full OpenGL 2.1 specification for 3D graphics.
And while screen captures currently aren’t available to support the claims as with the video hardware, the slip also hints that 10.5.7 is the first edition of Mac OS X to recognize Intel’s Nehalem architecture.
The Nehalem architecture is a major overhaul to Intel’s standard hardware approach to processors and leaves aside the standard system bus in favor of an interface that lets the processors talk directly to memory, peripherals and each other.
Although it’s unknown as to whether Apple will formally include the new hardware support in the release of Mac OS X 10.5.7, such add-ons will eventually become necessary. It’s been rumored that Apple is looking to use Intel’s Nehalem-based Xeon processors at the heart of its next generation of Mac Pro workstations and will eventually filter the technology down to its portables and mainstream desktops through Core i7 processors, which share the same essential design.
Apple has also remained comparatively dormant in its support for AMD’s ATI Radeon graphics and hasn’t used hardware newer than the Radeon HD 2600 found in the iMac and as an option for the Mac Pro; the technology is now approximately two generations old.
Stay tuned for additional details as they become available and let us know what you think in the comments or forums.
