Mac OS X version 10.6 SnowLeopard
The next big things
Snow Leopard is here! -- Stop in and get it today!
Refined, not reinvented
Mac OS X is renowned for its simplicity, its reliability, and its ease of use. So when it came to designing Snow Leopard, Apple engineers had a single goal: to make a great thing even better. They searched for areas to refine, further simplify, and speed up — from little things like ejecting external drives to big things like installing the OS. In many cases, they elevated great to amazing. Here are just a few examples of how your Mac experience was fine-tuned.
A more advanced, more nimble Finder
The Finder has been completely rewritten in Cocoa to take advantage of all the modern technologies in Mac OS X, including 64-bit support and Grand Central Dispatch. It’s more responsive from top to bottom, with snappier performance throughout the Finder. And it includes new features such as customizable Spotlight search options and an enhanced icon view that lets you thumb through a multipage document or watch a QuickTime movie.
New look, new features for Exposé and Stacks
Exposé is refined and more convenient. It’s now integrated in the Dock, so you can just click and hold an application icon in the Dock and all the windows for that application will unshuffle so you can quickly change to another one. Exposé also has a whole new look. Windows are displayed in an organized grid, making it even easier to find what you’re looking for. And stacks — Dock items that give you fast access to a folder of files — are now scrollable, so you can easily view all items. You can also navigate through folders in a stack to see all the files inside it.

Quicker Time Machine backup
Introduced in Mac OS X Leopard, the revolutionary Time Machine made backing up your hard drive easy for the first time. Time Capsule took backup even further with its wireless hard drive that works seamlessly with Time Machine. Now Snow Leopard makes Time Machine up to 80 percent faster and reduces the time it takes to complete your initial backup to Time Capsule.
Faster to wake up and shut down
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 when you’re trying to head home or to the airport.
More reliable disk eject
Snow Leopard improves the reliability of ejecting discs and external drives. Sometimes when an application or process is using the files on a drive, Mac OS X prevents you from ejecting it, but you don’t always know why. In Snow Leopard, you’ll get fewer of those errors and when you do get them, you’ll see exactly which application is using the drive, so you can quit it and eject the drive properly.
More efficient file sharing
The Bonjour technology in every Mac makes file and media sharing virtually effortless. Now Bonjour in Snow Leopard makes sharing more energy efficient. If you have a computer in your home or office that shares files — like media files for your Apple TV — you have to leave the computer on all the time, which isn’t very energy efficient. With Snow Leopard and a compatible AirPort Extreme or Time Capsule base station, however, your computer can go to sleep yet continue to share its files with other computers and devices, waking when you need it and sleeping when you don’t.
And much more!
