Mac OS X Snow Leopard (version 10.6) is the seventh and current
major release of
Mac OS X,
Apple's desktop and server
operating system for
Macintosh computers.
Snow Leopard was publicly unveiled on June 8, 2009 at the
Apple Worldwide Developers Conference. On August 28, 2009, it was released worldwide,
[2] and was made available for purchase from Apple's website and its retail stores at the price of US$29 for a single-user license. As a result of the low price, initial sales of Snow Leopard were significantly higher than that of its predecessors.
[3] The release of Snow Leopard came nearly two years after the introduction of
Mac OS X v10.5 "Leopard", the second longest time span between successive Mac OS X releases
Unlike previous versions of Mac OS X, the goals with Snow Leopard were improved performance, greater efficiency and the reduction of its overall
memory footprint. Addition of new end-user features was not a primary goal. Much of the software in Mac OS X was extensively rewritten for this release in order to fully take advantage of modern
Macintosh hardware. New programming frameworks, such as
OpenCL, were created, allowing software developers to use
graphics cards in their applications. This is also the first Mac OS release since the introduction of
System 7.1.2 that does not support the
PowerPC architecture, as Apple now intends to focus on
its current line of
it has a crazy interface for computer lovers it is one of the best things that has ever happened in the mac OS
whao this is wonderful, With Snow Leopard, your Mac wakes from sleep up to twice as quickly when you have screen locking enabled. And shutting down is up to 80 percent faster, saving precious moments .
Another benefit of the 64-bit applications in Snow Leopard is that they’re even more secure from hackers and malware than the 32-bit versions. That's because 64-bit applications can use more advanced security techniques to fend off malicious code.
First, 64-bit applications can keep their data out of harm's way thanks to a more secure function argument-passing mechanism and the use of hardware-based execute disable for heap memory. In addition, memory on the system heap is marked using strengthened checksums, helping to prevent attacks that rely on corrupting memory.64-bit applications in Snow Leopard deliver faster performance at common operations.
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. And new 64-bit applications work just fine with your existing storage devices, PCI cards, and Snow Leopard-compatible printers.
