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.

Apple EFI Update Fries Vista Installs

If you have an Intel Mac with Vista on Boot Camp… prepare to reinstall Vista after applying the latest EFI update. The Apple CSM (Boot Camp) runtimes have changed, and because Vista is semi-EFI and GPT sensitive… changing those runtimes fries the install. The good news is that Apple made these changes now so that when Vista comes out users won’t have to reinstall.

Update: Running Windows Startup Repair does try to fix the problem, but does not fix it fully. Windows will still not boot.

The Apple Core: Inside Apple’s new Core 2 Duo chip

Apple released a significant update to the MacBook Pro yesterday adding a new Core 2 Duo T-series processor to the mix. Let’s take a look at what’s changed.
Core 2 Duo Microprocessor
Apple has upgraded the MacBook Pro to the latest Intel silicon and the Core 2 Duo chip features a 64-bit architecture. Unfortunately, Mac OS 10.4 is only a 32-bit OS. The good news is that Apple has promised that Mac OS 10.5 (Leopard) and most of their software will be 64-bit aware by the time Leopard is released in the Spring of 2007.
The other significant bump in the Core 2 Duo processor is that it ships with 4MB of Level 2 cache, double the L2 cache in the previous MacBook Pro. That alone should add a noticeable performance jump in the new MacBook Pro.

Intel is cool with Apple keeping its entire user experience to a closed platform despite its underlying complexities, at least according to Eric Kim of Intel’s Digital Home Group. He told reporters at the CEATEC exhibition in Japan that “Clearly, Apple’s orientation is to deliver the best possible user experience from end to end by being closed. That’s what they do, and they are very, very good at it.” He went on to say: “We have a little motto inside Intel: ‘Let Apple, be Apple.’ We are happy to serve them,” he said.
