Separate a tab into its own window with a simple drag and drop.
Easily Create Tabbed Bookmarks
Set a bookmark for an entire set of tabs so that you can view them later, all at once.
Merge All Windows
Combine all your open browser windows into one single, tabbed window.
Full History Search
Easily find web pages you have visited. Safari indexes all of the text in websites that you browse. Even weeks later, Safari will be able to find a web page that matches your search.
Reopen Windows
Go back to a set of windows you were viewing after closing them or even after quitting Safari.
Resizable Text Fields
Resize any text field to the size you want because the original design was too small or you just have a lot to say. The contents of the web page will reflow to make room for the resized text field.
Preview Controls for PDFs
Gain new control over PDFs you see on the web. With Preview controls built into Safari, you can zoom in and out, navigate PDF pages with the sidebar, even open the PDF in a separate Preview window.

Create a screen saver mosaic. Choose any picture screen saver or one of your iPhoto albums and Leopard will turn it into a beautiful mosaic on the fly.
Back to top SecurityTagging Downloaded Applications
Protect yourself from potential threats. Any application downloaded to your Mac is tagged. Before it runs for the first time, the system asks for your consent — telling you when it was downloaded, what application was used to download it, and, if applicable, what URL it came from.
Signed Applications
Feel safe with your applications. A digital signature on an application verifies its identity and ensures its integrity. All applications shipped with Leopard are signed by Apple, and third-party software developers can also sign their applications.
Application-Based Firewall
Gain more control over the built-in firewall. Specify the behavior of specific applications to either allow or block incoming connections.
Stronger Encryption for Disk Images
Give your data even more security. Disk Utility now allows you to create encrypted disk images using 256-bit AES encryption.
Enhanced VPN Client Compatibility
Connect to a broader range of VPN clients. Leopard supports Cisco Group Filtering as well as DHCP over PPP, which allows you to dynamically acquire additional configuration options such as static routes and search domains.
Sharing and Collaboration Configuration
Share any folder on your Mac by setting it up as a shared folder in the Get Info window or in the Sharing pane of System Preferences. You can also create and edit access control lists, share with individuals in your network directory, or contacts in Address Book.
Sandboxing
Enjoy a higher level of protection. Sandboxing prevents hackers from hijacking applications to run their own code by making sure applications only do what they’re intended to do. It restricts an application’s file access, network access, and ability to launch other applications. Many Leopard applications — such as Bonjour, Quick Look, and the Spotlight indexer — are sandboxed so hackers can’t exploit them.
Multiple User Certificates
Have more flexibility in choosing a digital certificate for encrypting email messages. With support for multiple user certificates, you can use the Keychain application to associate your certificates with various email addresses.
Enhanced Smart Card Capabilities
Let your smart card do more. Now you can use a smart card to unlock FileVault volumes and your keychain, and configure your Mac to lock the screen when a smart card is removed. Leopard supports the PIV standard for Federal employees and contractors.
Library Randomization
Defend against attackers with no effort at all. One of the most common security breaches occurs when a hacker’s code calls a known memory address to have a system function execute malicious code. Leopard frustrates this plan by relocating system libraries to one of several thousand possible randomly assigned addresses.
Windows SMB Packet Signing
Enjoy improved compatibility and security with Windows-based servers.
Back to top SpacesSpaces
Organize your activities into separate spaces and easily switch from one to another. Make a space for work or play. Choose from a number of convenient options that make moving from space to space fast and easy.

Search any Mac on your network. Use Spotlight to find files just like you do on your Mac — by name, contents, or even metadata. You can search any connected Mac with Personal File Sharing enabled or a file server that’s sharing its files.
Advanced Searches
Use a richer search vocabulary. The Spotlight search field now supports Boolean logic with AND/NOT/OR and parenthesis syntax. Search category labels such as “author” or “width.” Use ranges in your search including “greater than” and “less than.” Spotlight also understands quoted phrases and dates.
Dictionary Definitions in Spotlight
Quickly find the definition of any word by entering it in the Spotlight search field.
Calculations in Spotlight
Find answers fast. Just activate Spotlight and type in a simple or sophisticated equation, and Spotlight will instantly show you the result. Enjoy support for over 40 functions ranging from simple math to logarithms to trigonometry.
Spotlight Application Launching
Launch applications quicker. The Spotlight default item is now the Top Hit, so if you search for an application, all you have to do is press Return to launch it.
Web History Search
Search your recently visited web pages with Spotlight. Spotlight indexes the names of the websites you have visited as well as the content in the sites themselves. Search any attribute of a recently visited web page and you can go right back to it in Safari.
Search by Filename
Find files faster. If you know the filename you’re looking for, narrow your search results so that Spotlight searches only filenames.
Search System Files
Use Spotlight to search system files.
Back to top SystemIcon Mode in Open and Save Panels
View your files as icons in the Open and Save panels, just as you would in the Finder.
iLife Media Browser in Open Panel
Access iLife content from any Mac OS X application. Now the iLife Media Browser is integrated into the Open panel.
Live Partition Resizing in Disk Utility
You may be able to gain disk space without losing data. If a volume is running out of space, simply delete the volume that comes after it on the disk and move the volume’s end point into the freed space.
Help Menu Search
Enjoy more helpful Help. A new search field in the Help menu displays all relevant menu items in the active application. Highlight one and Leopard opens the menu and highlights the command.
Guest Log-In Accounts
Allow anyone to surf the web and check email as a guest on your Mac. When they log out of the guest account, Mac OS X purges the account, removing any trace of their activity. So each time someone logs in as a guest, he or she gets a fresh, unused account.
Grammar Check
Let your grammar set a shining example. A built-in English language grammar checker helps ensure that you don’t make errors in grammar.
Scroll Non-Active Windows
Scroll any open window, even if it’s not active. Simply position your mouse over the target window and scroll.
