The most powerful Mac. With an OS to match.

Mac OS X is engineered to get the most out of the advanced architecture in the new Mac Pro. Built on a rock-solid UNIX foundation, Mac OS X delivers true 64-bit performance and incorporates industry-leading developer tools.

UNIX compliant.

What makes Mac OS X a powerful operating system is the technology behind it: a fully certified UNIX foundation. With a rock-solid UNIX infrastructure, it’s one of the most secure and stable operating systems on any platform. As a developer, you’ll appreciate Mac OS X even more because it’s fully UNIX compliant. That means it compiles and runs all your existing UNIX code, so you can deploy it in environments that demand full conformance. The result: Software performs exactly as it’s meant to. And because the powerful tools built into Mac OS X improve application performance on multicore processors, the new Mac Pro is the ideal workstation.

64-bit power.

Mac OS X is to the new Mac Pro what a skilled driver is to a car with a powerful engine — a perfect match. Since the entire operating system is 64-bit ready, you can take full advantage of the 64-bit architecture of the Quad-Core Intel Xeon “Nehalem” processors inside the new Mac Pro. Add to that the 32GB of memory available for the Mac Pro, and the performance of Mac OS X is even better than before. Mac OS X also enables developers to build complete 64-bit applications using the Cocoa, Quartz, OpenGL, and X11 GUI frameworks. And because Mac OS X supports 64-bit and 32-bit applications, you don’t need a new set of devices or drivers.

Multicore. Multitask.

At the heart of the new Mac Pro are one or two Quad-Core Intel Xeon “Nehalem” processors with an incredible amount of processing power. Optimized for multicore technology, Mac OS X provides powerful tools that make it easy to reap the benefits of the Mac Pro. The scheduler in Mac OS X, for instance, is very efficient at allocating tasks across multiple cores and processors. So Mac OS X spends less time managing tasks and more time performing computations. As a developer, you can build applications that execute the same efficiency, thanks to NSOperation, a breakthrough API that optimizes applications for multicore processing.

Core Animation.

From the cascading windows of Time Machine to the smooth animation of the reflective 3D Dock, stunning visual effects truly set Mac OS X apart. Behind all that beauty is a technology built into Mac OS X called Core Animation. The performance of Core Animation benefits from the multicore processors and advanced graphics hardware in the new Mac Pro. For developers, Core Animation easily opens up the power of Apple’s graphics technologies. You can create animated user interfaces and visualizations that simultaneously layer different media types, such as text, 2D graphics, OpenGL rendering, and QuickTime video, all in real time.

Xcode developer tools.

Xcode is the graphical development environment that comes with every Mac. It's the same software used by Apple to produce Mac OS X, and it's packed with tools and features, including a powerful graphical debugger, a code editor supporting dozens of languages, and the amazing Instruments tool to visualize your application's performance. Xcode is optimized to take advantage of the multicore Intel Xeon “Nehalem” processors and system memory in the Mac Pro. It performs 20 percent faster than before, supports multiple languages (both computer and human), and offers programmers everything they need to make stunning Mac OS X applications.*

Voilà. Instant server.

The multitalented Mac Pro can also act as a powerful small-workgroup server. Just add Mac OS X Server. The resulting solution combines Mac ease of use with flexible configuration options and server-class hardware. With 8-core Intel Xeon “Nehalem” processing power, up to 32GB of ECC memory, a new optional RAID card, and dual Gigabit Ethernet ports, a Mac Pro workgroup server has everything you need — and then some.

* Testing conducted by Apple in February 2009 using preproduction Mac Pro 8-core 2.93GHz units and shipping Mac Pro 8-core 3.2GHz units. Systems were configured with 6GB of RAM for Mac Pro 8-core 2.93GHz and 8GB of RAM for Mac Pro 8-core 3.2GHz. Xcode results based on build and clean time of Adium 1.3.2 . Performance tests are conducted using specific computer systems and reflect the approximate performance of Mac Pro.
