Apple has acknowledged an issue encountered by some Leopard users trying to install the company's latest update released Monday. In a support document posted to its site, Apple described an issue in which a Mac would hang on a "Configuring installation" window when trying to install Mac OS X 10.5.6. That was apparently the result of an incomplete update getting seeded into the Software Update process, and Mac OS X will freak out if it tries to install a partially downloaded update. Apple recommends that if you encounter this problem, or have already, that you force Software Update to quit, remove the partial update from your library, and re-download the update. If you chose to download the standalone update from Apple's site rather than the combo update, you might also have had this problem; when in doubt, choose the combo update option. If you've had a separate problem in trying to install the update, check out our sister site MacFixIt for tips and troubleshooting guidelines.

Apple's OS X Snow Leopard may be on tap for the start of the new year, slightly earlier than expected. The update appears to be slated for debut in the first quarter of 2009, according to a slide presented by Jordan Hubbard, Apple's director of engineering for Unix technologies, at a conference last week. Snow Leopard, or version 10.6 of the operating system, is expected to be optimized for multicore processors, include QuickTime X, and offer built-in support for Microsoft's Exchange 2007 software.

A slide presented on Friday by an Apple executive. Apple previewed Snow Leopard in June. At that time, Apple said that Snow Leopard was "scheduled to ship in about a year." Hubbard, presenting at LISA 08, or the Large Installation System Administration Conference, in San Diego on Friday showed a slide (PDF) that indicated Snow Leopard's debut would come in the first quarter of 2009, MacRumors.com reported late Tuesday. Hubbard's presentation raises speculation that Snow Leopard's debut could be pegged to the next MacWorld conference in San Francisco, which begins on January 5.

A Quantum Leap.

Since 2001, Mac OS X has delivered more than a thousand innovative new features. With Snow Leopard, the next major version of the world’s most advanced operating system, Mac OS X changes more than its spots, it changes focus. Taking a break from adding new features, Snow Leopard — scheduled to ship in about a year — builds on Leopard’s enormous innovations by delivering a new generation of core software technologies that will streamline Mac OS X, enhance its performance, and set new standards for quality. Snow Leopard dramatically reduces the footprint of Mac OS X, making it even more efficient for users, and giving them back valuable hard drive space for their music and photos.

Microsoft Exchange Support

Snow Leopard includes out-of-the-box support for Microsoft Exchange 2007 built into Mail, Address Book, and iCal. Mac OS X uses the Exchange Web Services protocol to provide access to Exchange Server 2007. Because Exchange is supported on your Mac and iPhone, you’ll be able to use them anywhere with full access to your email, contacts, and calendar.

 

Multicore

“Grand Central,” a new set of technologies built into Snow Leopard, brings unrivaled support for multicore systems to Mac OS X. More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central takes full advantage by making all of Mac OS X multicore aware and optimizing it for allocating tasks across multiple cores and processors. Grand Central also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems.

 

64-bit

To accommodate the enormous amounts of memory being added to advanced hardware, Snow Leopard extends the 64-bit technology in Mac OS X to support breakthrough amounts of RAM — up to a theoretical 16TB, or 500 times more than what is possible today. More RAM makes applications run faster, because more of their data can be kept in the very fast physical RAM instead of on the much slower hard disk.

Media and Internet

Using media technology pioneered in OS X iPhone, Snow Leopard introduces QuickTime X, a streamlined, next-generation platform that advances modern media and Internet standards. QuickTime X features optimized support for modern codecs and more efficient media playback, making it ideal for any application that needs to play media content.

Because Snow Leopard delivers the fastest implementation of JavaScript to date, web applications are more responsive. Safari runs JavaScript up to 53 percent faster with Snow Leopard.*

OpenCL

Another powerful Snow Leopard technology, OpenCL (Open Computing Language), makes it possible for developers to efficiently tap the vast gigaflops of computing power currently locked up in the graphics processing unit (GPU). With GPUs approaching processing speeds of a trillion operations per second, they’re capable of considerably more than just drawing pictures. OpenCL takes that power and redirects it for general-purpose computing.

사실 많이 기대하고 있지만 실제로 작업용 컴퓨터에 설치하기엔 시간이 조금 더 필요할 것 같다. 어쨋거나 내년 초에 그 모습을 볼 수 있을 것 같으니 실로 두근거린다.

Ableton has updated Live to v7.0.14.

Improvements:

• Updated Manual.
• On Mac OS X, changing the audio buffer size requires you to click on an 'Apply' button to commit the new buffer size. This should avoid that Audio Unit plug-ins are re-created more than once when changing the buffer size.

Bug fixes:

• Deleting or moving a Rack chain while there are clip envelopes for one of the chain mixer's parameters (volume, pan, or sends) could crash Live.
• MIDI overdub during Arranger recording could delete or cut notes.
• Selecting a scene would display "Insert Scene" for the "Select All" menu entry.
• Under very rare conditions and only with a Live set having at least 48 tracks, certain routings could switch to 'None' after previewing aLive clip or MIDI file.
• Replacing an instrument inside a Rack with a track having additional automation lanes controlling parameters of the previous instrument would crash Live.
• Dragging a clip from within Live or from the Browser would not use the Default preset.
• When running Live as ReWire master with Propellerheads Reason as ReWire slave, under certain conditions Live would crash when switching presets in Reason in a way that would modify or change its MIDI targets.
