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.
Expos?© 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. Expos?© 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.
Faster, more reliable installation.
Upgrading your Mac has never been easier. For Snow Leopard, the entire process has been simplified, streamlined, and is up to 50 percent faster, yet more comprehensive and reliable.2 For example, Snow Leopard checks your applications to make sure they?€™re compatible and sets aside any programs known to be incompatible. In case a power outage interrupts your installation, it can start again without losing any data.
Snow Leopard takes up less than half the disk space of the previous version, freeing about 7GB for you ?€” enough for about 1,750 more songs3 or a few thousand more photos.
Another leap forward for QuickTime.
QuickTime X is the next-generation media technology that powers the audio and video experience in Mac OS X Snow Leopard. It includes a completely new QuickTime Player application with a clean, uncluttered design, a new trimming interface, and easy uploads to YouTube and MobileMe. And it delivers more efficient media playback, HTTP-based live streaming, and greater color accuracy.\
