As much as the Hackintosh community may love Mac OS X, Apple doesn’t always love them back.

Per OSXDaily, support for Intel’s Atom processor is confirmed to be missing in the final release of 10.6.2.

Apple’s latest update for Snow Leopard has broken support for Intel’s Atom processor line. Mac OS X 10.6.2 was released Monday afternoon, and was Apple’s second major update for Snow Leopard.

OSXDaily reported that various netbook and “hackintosh” forums are “blowing up with problems of 10.6.2 instant rebooting their Atom-based notebooks.” Systems using the Atom processor will go into a startup-loop if the 10.6.2 update is installed.

Support for Atom fluctuated over the course of 10.6.2 development, and Apple was mum about the subject.

It is recommended that anyone using OS X on Atom-based systems should not install the update. Many believe that a community-generated fix will be developed soon. Prominent hackintosh blogger StellaRola commented, “Just an FYI, this is OSx86 after all and none of the scenes hackers really let down on support. The latest kernel may not be “officially” supported but that doesn’t mean there won’t be a modded kernel around the corner.”

Intel’s Atom processor is a low-cost, low-power chip intended for notebooks, netbooks and ultra-mobile PCs. Although current Apple products do not sport the Atom chips, a dedicated community has formed around the practice of installing Snow Leopard on Atom netbooks.

Samsung Releases 1GHz Hummingbird Processor for Future Smartphones

Electronics giant Samsung unveiled a new ARM processor intended for future smartphones. Per MacNN, the processor, nicknamed “Hummingbird”, uses the same Cortex-A8 architecture as the chip in the iPhone 3GS but clocks at 1GHz, significantly higher than the 833MHz of its previous best. The feat is accomplished both by a smaller, more energy-efficient 45 nanometer process as well as partly customized circuits designed to handle the load.

Samsung has stated the processor can handle up to 2 billion instructions per second but will consume only 640mW of power and doesn’t need more than 1V of voltage. As a Cortex-A8 chip, Hummingbird is a dual-issue (two instructions at a time) processor with special media extensions, known as Neon, that can speed up common audio or video tasks.

Specific customers haven’t been named for the processor, although Samsung makes it clear it sees Hummingbird reaching “advanced mobile devices” once it’s turned into standard system-on-chip processors. Apple has been one of Samsung’s larger customers for ARM processors, although it has typically underclocked the processor for the iPhone to accommodate the heat concerns in the tight enclosure.

Intel May Release Updated Nehalem Processors Next Month

Processor giant Intel looks ready to deliver a new line of server, notebook and desktop processors based on its new Nehalem microarchitecture next month. According to DigiTimes, the new chips will cut down on bottlenecks that plague its current chips as well as be able to execute more tasks while drawing less power.

An industry source with knowledge of Intel’s plans said the company will deliver new Xeon server processors belonging to the 5500 and 3500 chip families starting early August. Chip specifics weren’t immediately available. The Mac Pro lineup introduced by Apple in March runs on Xeon 5500 ad 3500 chips.

Additional reports have stated that Intel will bring its latest chip microarchitecture to high-end mainstream desktops and laptops starting in September. The company will launch quad-core desktop chips code-named Lynnfield in early September, followed by quad-core laptop chips code-named Clarksfield later in the month, according to the report, which cited industry sources.

Intel officials declined comment, saying the company doesn’t talk about rumors. “But I can say that Lynnfield and Clarksfield are on track for second-half 2009 production,” an Intel spokesman said in an e-mail.

The Lynnfield and Clarksfield chips will be manufactured using the 45-nanometer process, according to Intel’s road map, and should be shipped before its shift to the more efficient 32-nm manufacturing process later this year.

The company is also slated to launch chips for new ultrathin laptops (the Celeron SU2300 and Celeron 743 processors) in September per the Digitimes report.

The Nehalem architecture integrates a memory controller into a CPU and provides a faster pipe for the processor to communicate with system components like a graphics card and other chips. It also allows execution of two software threads simultaneously, so a system with four processor cores could run eight threads simultaneously for quicker application performance. The chips will be manufactured using the 45-nanometer process.

While the new Nehalem chips may be limited to desktops and laptops on the higher price band, affordably priced systems could see new chips when Intel switches to the 32-nm process. The 32-nm chips will integrate a graphics processor and CPU in one chip, which could boost graphics performance while drawing less power than existing processors.

Intel Readying Ultra-Low-Voltage Processors for Ultraportable Notebooks

Processor giant Intel reaffirmed on Friday that the company is readying a new series of new ultra-low-voltage chips, due in the second quarter, for inexpensive ultraportable notebooks.
According to Macworld UK, the company will ship the ULV chips as part of its Montevina Plus mobile laptop platform, an updated version of the existing Montevina platform, a fact confirmed by company spokeswoman Connie Brown.
The processors could be used in small, thin notebooks and provide the same level of functionality as notebooks priced above US$1,500.
Notebooks currently based on Intel’s ULV chips could be as thin as Apple’s MacBook Air or Dell’s recently launched Adamo, with prices ranging between US$599 and US$1,299.
Intel’s new series could fit into smaller spaces and use less power than the existing Core 2 Duo ULV line, which uses about 10 watts of power and is generally found in ultraportable notebooks such as Apple’s MacBook Air.
Intel’s Montevina Plus platform also will offer new chips running as fast as 3.06GHz, for mainstream notebooks priced between $399 and $1,499.
The company’s Montevina Plus is likely to be Intel’s most important update to its laptop platforms before the company starts shipping its new Arrandale chips for laptops later this year. The Arrandale chips will be manufactured using a 32-nanometer process and integrate a graphics processor and CPU in one chip, which could boost graphics performance while drawing less power than existing Core 2 processors. The Arrandale chips are also expected to be more energy-efficient, which could improve notebook battery life.
Expected clock speeds on Arrandale processors should be similar to processors used in existing laptops while offering better performance by running applications through more threads while drawing less power.
Stay tuned for additional details as they become available and let us know what’s on your mind in the comments or forums.
