    Mac OS 10.6 Information (If you didn't know)

    Post by Ralph on 27th October 2009, 12:38 am

    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.

    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.1

    Faster at common tasks.
    Wake up 2x
    Shut down 1.8x
    Times faster than Leopard.¹

    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.


    Smaller footprint.

    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.

    Defense against viruses and other malware.

    With virtually no effort on your part, Mac OS X offers a multilayered system of defenses against viruses and other malicious applications, or malware. For example, it prevents hackers from harming your programs through a technique called “sandboxing” — restricting what actions programs can perform on your Mac, what files they can access, and what other programs they can launch. Other automatic security features include Library Randomization, which prevents malicious commands from finding their targets, and Execute Disable, which protects the memory in your Mac from attacks.


    The 64-bit applications in Snow Leopard are even more secure from hackers and malware than the 32-bit versions. That's because 64-bit applications can use more advanced security techniques to fend off malicious code. Learn more about 64-bit


    Always on the alert.
    Innocent-looking files downloaded over the Internet may contain dangerous malware in disguise. That’s why files you download using Safari, Mail, and iChat are screened to determine if they contain applications. If they do, Mac OS X alerts you, then warns you the first time you open one. You decide whether to open the application or cancel the attempt. And Mac OS X can use digital signatures to verify that an application hasn’t been changed since it was created.


    Stay up to date. Automatically.
    When a potential security threat arises, Apple responds quickly by providing software updates and security enhancements that can be downloaded automatically and installed with a click. Apple works with the incident response community, including the Forum of Incident Response and Security Teams (FIRST) and the FreeBSD Security Team, to proactively identify and quickly correct operating system vulnerabilities. In addition, Apple cooperates closely with organizations such as the Computer Emergency Response Team Coordination Center (CERT/CC).


    Easy to customize.
    With Mac OS X, it’s easy to customize and use security features. Setting up secure file sharing, for example, involves a quick trip to System Preferences. FileVault lets you encrypt all the files in your home folder with just a few clicks and a password of your choosing. The firewall comes preconfigured to block online intruders, but it’s easy to make whatever changes you want.
