Quick Look at Snow Leopard

Mac OS X Snow Leopard is an even more powerful and refined version of the worlds most advanced operating system. Snow Leopard builds on the success of Leopard with hundreds of refinements, out-of-the-box support for Microsoft Exchange, and new core technologies that take advantage of the powerful hardware in every Mac. It enhances the entire Mac experience in big ways and small, making the Mac more reliable and easier to use.

RefinementsFrom installation to shutdown, Mac OS X Snow Leopard includes hundreds of improvements that will help make your Mac faster, more responsive, and more reliable than ever. Mac OS X Snow Leopard provides key refinements in many areas, including the following: Dock. Now integrated right in the Dock, Expos gives you a quick and easy way to see all of the open windows of an application. In the Dock, simply click and hold an application icon: All of the open windows unshue on the desktop so you can quickly locate a window and move right to it. Finder. The Finder has been completely rewritten using the modern Cocoa framework in Mac OS X, taking advantage of the new technologies in Snow Leopardincluding 64-bit support and Grand Central Dispatch. The familiar Finder interface is unchanged, but you will discover the Finder is faster and more responsive. It also includes an enhanced icon view with live file previews, so you can thumb through a multipage document or even watch a QuickTime movie. Installation. Snow Leopard makes upgrading your Mac easier than ever. The entire installation process is simpler and more streamlined, and is now up to 50 percent faster.1 Refinements make installation more reliable as well. Once installed, Snow Leopard actually frees up about 7GB of space on your computer. QuickTime X. The next-generation media technology, QuickTime X powers the audio and video experience in Snow Leopard. It debuts a completely new QuickTime Player application with a clean, uncluttered interface as well as an easy way to record, trim, and share your media. Preview. Preview in Snow Leopard includes a number of refinements that make it even better for viewing PDFs and image files. Preview delivers increased performance for opening PDFs and JPEGs, and brings accurate text selection to multicolumn PDFs. Sophisticated artificial intelligence algorithms infer the layout of each page to identify the columns. So now when you select text from a particular column, Preview gives you just the text you need.

Safari 4. The latest version of Apples blazing-fast web browser includes a range of great new features like Full History Search, Smart Search and Smart Address fields, and an innovative way to view your most frequented sites called Top Sites. In Snow Leopard, 64-bit technology improves JavaScript performance in Safari 4 by up to 50 percent.2 Safari 4 is also more resistant to crashes because plug-ins now run separately from the browser. If a plug-in crashes, Safari keeps running. Universal Access. Snow Leopard advances the built-in VoiceOver technology that makes Mac OS X accessible for those who are blind or have low vision. It includes a unique way to control and navigate the Mac using the Multi-Touch trackpad. Performance. Snow Leopard delivers a number of performance improvements across the system that speed up many of the common tasks you do on your Mac. To name a few: Installation is up to 50 percent faster than Leopard1; wake from sleep is as much as 2 times faster; shutdown is up to 1.8 times faster; initial Time Machine backups to Time Capsule are up to 80 percent faster than Leopard.2

Exchange SupportSnow Leopard includes out-of-the-box support for Microsoft Exchange Server 2007 in Mail, iCal, and Address Book, so its easier than ever to take your Mac to work. You get the features you expect from Exchangelike email, contacts, calendar invitations, and access to the Global Address Listwhile also enjoying the powerful and innovative features in Mac OS X such as Spotlight for instantly searching through all of your mail, Quick Look for previewing attachments, and Data Detectors for acting on important information in an email message.

New TechnologiesEvery new Mac ships with a new generation of hardware that includes gigabytes of RAM, 64-bit dual-core processors, and graphics processing units that are capable of enormous raw processing power. Snow Leopard includes advanced technologies that enable developers to take advantage of this incredible hardware in their applications. These technologies make Mac OS X Snow Leopard the worlds most advanced operating system and set up the Mac for future innovation. 64-bit. Computing with 64-bit technology shatters the 32-bit memory limit by enabling applications to address a theoretical 16 billion gigabytes of memory. All major applications in Snow Leopard have been written in 64-bit so they can address all of that memory as well as perform faster.3 Snow Leopard makes the transition to 64-bit simple, with one version of the operating system that runs both 64-bit and 32-bit applications. Grand Central Dispatch. The performance in todays processors is being driven by more cores, not faster clock speeds. Grand Central Dispatch (GCD) is a revolutionary approach to multicore computing. Woven throughout the fabric of Snow Leopard, GCD combines an easy-to-use programming model with highly efficient system services to radically simplify the code needed to optimize the multiple processors. OpenCL. The performance of graphics processing units (GPUs) has grown exponentially, with the most powerful GPUs capable of more than 1 trillion operations per second (1 teraflop). OpenCL in Snow Leopard takes the power of the GPU beyond graphics, making it available for general-purpose computing. OpenCL is an open standard supported by the biggest names in the industry, including AMD, NVIDIA, and Intel.

The Dock provides users with an easy way to quickly access the applications, folders, and files they use most from a convenient location at the bottom of the screen. Snow Leopard includes a number of refinements that make the Dock even better, including Dock Expos so you can instantly view the open windows of an application as well as conveniently scroll through and navigate folders in stacks.

Dock ExposExpos has a whole new look in Snow Leopard. Open windows are now displayed in an organized grid, making it even easier to find the one you are looking for. Using the tab key, you can flip through all running applications to preview the open windows. Windows in Expos are spring-loaded, so you can drag and drop items between windows. For example, if you drag a document from the Finder onto the Mail icon, Expos instantly activates, showing you all of your Mail windows so you can add the document as an attachment.Easily reorganize your windows You can reorganize the windows using keyboard shortcuts: Press Command-1 to arrange the windows alphabetically; press Command-2 to arrange by application.

Expos is more convenient than ever in Snow Leopard. Click and hold an application icon in the Dock: All of the applications open windows instantly unshue on the desktop, making it easy to find the window you are looking for.
