Since 2001, the breakthrough technologies and rock-solid UNIX foundation of Mac OS X have made it not only the world’s most advanced operating system but also extremely secure, compatible, and easy to use. Snow Leopard continues this innovation by incorporating new technologies that offer immediate improvements while also smartly setting it up for the future.
New Features
64-Bit
The next big step for the Mac. All key system applications are now 64-bit so they can take advantage of all the memory in your Mac.Nearly all system applications — including the Finder, Mail, Safari, iCal, and iChat are now built with 64-bit code. Today’s Mac computers can hold up to 32GB of physical memory, but the 32-bit applications that run on them can address only 4GB of RAM at a time. 64-bit computing shatters that barrier by enabling applications to address a theoretical 16 billion gigabytes of memory, or 16 exabytes. To ensure simplicity and flexibility, Mac OS X still comes in one version that runs both 64-bit and 32-bit applications. So you don’t need to update everything on your system just to run a single 64-bit program.
Grand Central Dispatch
A revolutionary new way for software to take advantage of multicore processors. More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central Dispatch 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 Dispatch also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems. Developers will program for Grand Central Dispatch using the Xcode tools included with every Mac.
OpenCL
A new technology that unleashes the power of graphics processors to accelerate application performance. With graphics processors surpassing speeds of a trillion operations per second, they’re capable of considerably more than just drawing pictures. OpenCL in Snow Leopard is a technology that makes it possible for developers to tap the vast computing power currently in the graphics processor and use it for any application. OpenCL automatically optimizes for the kind of graphics processor in the Mac, adjusting itself to the available processing power. OpenCL provides consistent numeric precision and accuracy, fixing a problem that has hampered GPU-based programming in the past.
QuickTime X
Snow Leopard introduces QuickTime X, a major leap forward that advances modern media and Internet standards. QuickTime X includes a brand-new player application, offers optimized support for modern codecs, and delivers more efficient media playback, making it ideal for any application that needs to play media content. Because it’s built into the heart of Snow Leopard, QuickTime X uses Mac OS X technologies such as Cocoa, Up to 2.8x FasterGrand Central Dispatch, and 64-bit computing to deliver greatest-possible performance and enables QuickTime Player to launch up to 2.8x faster.
Microsoft Exchange Server Support
Mac OS X Snow Leopard delivers built-in support for Microsoft Exchange Server, something even Windows PCs don’t have. So you can use your Mac — with all the features and applications you love — at home and at work and have all your messages, meetings, and contacts in one place. Now with Snow Leopard, the Mac is compatible with Microsoft Exchange Server 2007, the most popular messaging and collaboration software in corporate environments.
