Features

Desktop
From the menu bar to the stunning new Dock, the Leopard desktop isnt just about design. Its about enjoying the time you spend on your computer and getting more out of it.
Start from the top. The menu bar hovers transparently above your workspace, letting the desktop image perhaps a favorite from your iPhoto library take center stage. Dock icons rest on a reflective floor with a bright active application signal. And the look of Leopard extends to all applications: Every window has a consistent design theme, and active applications are even more distinct, casting deeper shadows.
Take a look at your desktop. Is it cluttered with files you downloaded or saved there (somewhat less than) temporarily? You're not alone. Everybody does it. Time to clean house with Stacks a brand-new feature in Leopard. Create Stacks from anything you want to access quickly from one place: a handful of documents, a group of applications, an entire folder. Files you download in Safari or save from an email are automatically directed to a Stack in the Dock, and when the download is complete, the Stack signals that a new item has arrived. When you want to see the files in a Stack, all you have to do is click Stacks spring open from the Dock in an elegant arc for a few items, or in an at-a-glance grid for more. Pretty neat.

Finder
Imagine if browsing the files on your Mac was as easy as browsing music in iTunes. Thats the idea behind the new Finder in Leopard. Now you can access everything on your system from an iTunes-style sidebar and flip through your files using Cover Flow.
Leopard brings new power to your old friend, the sidebar. Now items are grouped into categories: places, devices, shared computers, and searches just like the Source list in iTunes. So with a single click, youre on your way to finding what you need.
Bring your files to life with Cover Flow in the Finder. Just as you use Cover Flow to flip through album art in iTunes, now you can use it to flip through your files. Cover Flow displays each file as a large preview of its first page. And you can page through multipage documents or play movies.
Stop looking and start finding with Cover Flow and Spotlight. Click a prebuilt search like yesterday or all images in the sidebar and Cover Flow displays your search results in the perfect at-a-glance format. Leopard comes with a number of helpful prebuilt searches, but its easy to create your own customized searches as well.
With shared computers automatically displayed in the sidebar, its far easier to find or access files on any computer in your house, whether Mac or PC. All it takes is a click. But heres where things get really interesting. By clicking on a connected Mac, you can see and control that computer (if authorized, of course) as if you were sitting in front of it. You can even search all the computers in the house to find what you're looking for.
ver need something on your Mac when you were thousands of miles from home? With Back to My Mac and a .Mac account, you can connect to any of your Macs at home from any Mac on the Internet. Your home computers will appear in the shared section of the sidebar just as they do when youre in the living room.
From the Finder or the menu bar, Spotlight in Leopard lets you search for more specific sets of things. Use Boolean logic to narrow search results by entering AND, OR, or NOT into a search request. You can also search for exact phrases (using quotation marks), dates, ranges (using greater than [>] and less than [<] symbols), absolute dates, and simple calculations.

Quick Look
sing Quick Look in Leopard, you can view the contents of a file without even opening it. Flip through multiple-page documents. Watch full-screen video. See entire Keynote presentations. With a single click.
So youre flipping through files in the Finder. But youre looking for something specific and you dont have time to open lots of files to find it. Enter Quick Look. It gives you a sneak peek of entire files even multiple-page documents and video without opening them.
uick Look works with nearly every file on your system, including images, text files, PDFs, movies, Keynote presentations, and Microsoft Word and Excel files. Click the Quick Look icon or tap the Space bar to see a file in Quick Look. Then click the arrow icon to see the same file full screen even video as it plays.

Time Machine
ore than a mere backup, Time Machine makes an up-to-date copy of everything on your Mac digital photos, music, movies, TV shows, and documents so you can go back in time to recover anything.
You can start using Time Machine in seconds. The first time you attach an external drive to your Mac, Time Machine asks if youd like to use that drive as your backup. Say yes and Time Machine takes care of everything else. Automatically. In the background. Youll never have to worry about backing up again.
Time Machine keeps an up-to-date copy of everything on your Mac. That includes system files, applications, accounts, preferences, music, photos, movies, and documents. But what makes Time Machine different from other backup applications is that it not only keeps a spare copy of every file, it remembers how your system looked on any given day so you can revisit your Mac as it appeared in the past.
Enter the Time Machine browser in search of your long-lost files and you see exactly how your computer looked on the dates youre browsing. Select a specific date, let Time Machine find your most recent changes, or do a Spotlight search to find exactly what youre looking for. Once you do, click Restore and Time Machine brings it back to the present. Time Machine restores individual files, complete folders, or your entire computer putting everything back the way it was and where it should be.
With a hard disk connected to your AirPort Extreme Base Station, all the Macs in your house can use Time Machine to back up wirelessly. Simply select your AirPort Disk as the backup disk for each computer and the whole family can enjoy the benefits of Time Machine.
Customize Time Machine by modifying the following behaviors in System Preferences:
Backup disk. Change the drive or volume youre backing up to. Or back up to a Mac OS X Server computer.
Do not back up. By default, Time Machine backs up your entire system. But you can also select items youd rather not back up.
Encrypt backup data. Turn on encryption to store your backup securely.
Backup storage time limits. Manage older backups so your backup drive doesnt fill up.

Spaces
You do a lot on your Mac. So what happens when projects pile up? Easy. Use Spaces to group your windows and banish clutter completely. Leopard gives you a Space for everything and puts everything in its Space.
Create a Space for work. Create a Space for play. Organize each Space the way you want it just by dragging in windows. Keep all your work projects in one Space and that fun flick you made in iMovie in another. Create a communication Space for iChat and Mail. You can even rearrange your Spaces with drag-and-drop ease shift a Space and every window in it comes along for the ride.
Moving from Space to Space is easy. Get a birds-eye view and select the Space you want or toggle between Spaces using the arrow keys. Even the Dock is down with Spaces: When you click a Dock icon, Leopard whisks you to the Space (or Spaces) where you have that application open.
