    Security

  238. Tagging 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.

  239. 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.

  240. Application-Based Firewall

  245. 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.

  246. 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.

  247. 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.

  248. 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.

  249. Windows SMB Packet Signing

    Enjoy improved compatibility and security with Windows-based servers.

  271. Guest Login Accounts

    Allow anyone to surf the web and check email as a guest on your Mac. When your guest logs out, Mac OS X purges the account, removing any trace of activity. So each time someone logs in as a guest, he or she gets a fresh, unused account.

That includes system files, applications, accounts, preferences, music, photos, movies, and documents.

  304. Automatic Backup

    Enjoy effortless setup. The first time you attach an external drive to your Mac, Time Machine asks if you’d like to use that drive as your backup. Say yes and Time Machine takes care of everything else. Automatically. In the background. You’ll never have to worry about backing up again.

  305. Go Back In Time

    See what your computer looked like in the past. Select a specific date and let Time Machine find your most recent changes, or do a Spotlight search to find exactly the file you’re looking for. Once you do, click Restore and Time Machine brings it back to the present.

  306. Automatic Stop and Resume

    Never skip a beat. If your Time Machine backup is interrupted — because you took your portable on the road or put your Mac to sleep — Time Machine will simply stop backing up. When you reconnect to your backup drive again, Time Machine automatically picks up where it left off.

  307. Do Not Back Up List

    Be selective. By default, Time Machine backs up your entire system. But you can also select items to exclude from a Time Machine backup to save space on your backup disk.
