Just picked this up at the local store, thought I'd share it with PB.
Mac OS X Snow Leopard and OS X 10.6.2 Combo Updater
Instructions:
1. Download and unzip the file.
2. Delete the zipped version if you wish as you now have SITX file versions.
3. Put all the SITX files into one folder, any folder.
5. Use Stuffit Expander to expand the archives and reveal the two disk images.
4. Do this by choosing 'part 1' of the SITX archives and choosing 'expand'.
6. You will NOT be able to use STARTUP DISK to boot to the DVD if you choose to burn it to a DVD.
7. You must either 'restore' it using Disk Utility to a partition with about 8 gigabytes of hard drive space from which you can boot and install OS X. Or, you should burn the DVD to an empty DVD+R from which you can boot and install OS X.
8. The ONLY way to boot using either method from step 7 is to power on your Macintosh and hold down the Option key until a list of bootable devices appear.
9. Choose Snow Leopard Install DVD from that list.
10. Follow the on-screen instructions from there.
From Wikipedia:
Mac OS X Snow Leopard (version 10.6) is the seventh major release of Mac OS X, Apple's desktop and server operating system. Apple CEO Steve Jobs announced Snow Leopard at WWDC on June 9, 2008, and it was privately demonstrated to developers by Senior Vice President of Software Engineering, Bertrand Serlet. A first public demonstration was given at WWDC 2009 by Serlet and Phil Schiller, Senior Vice President of Worldwide Marketing.[2]
This version of Mac OS X focuses on improving performance, efficiency and reducing its overall memory footprint compared to its predecessor Mac OS X v10.5 'Leopard', rather than new end-user features. This is also the first Mac OS release since the introduction of System 7.1.2 that does not support the PowerPC architecture, as Apple now intends to focus on its current line of Intel-based products.[2]
Snow Leopard was released on August 28, 2009,[3] and is available as an upgrade for Intel-based Macintosh computers. Single-user licenses and 'family pack' licenses for up to five computers are available, and for qualifying Mac computers bought after June 8, 2009, Apple offers a discounted price through their 'up to date' program. While the license for the standalone retail version of Snow Leopard restricts that upgrade to users of Mac OS X v10.5 'Leopard', the company has acknowledged that there is no technical barrier preventing a direct upgrade from Mac OS X v10.4 'Tiger'.[4] The recommended upgrade path for OS X 'Tiger' is through the current release of the 'Mac Box Set', which includes OS X Snow Leopard, iLife '09, and iWork '09.
System requirements
Apple states the following basic Snow Leopard system requirements, although, for some specific applications such as QuickTime H.264 hardware acceleration support and OpenCL, a supported GPU is required (NVIDIA GeForce 8600M GT or ATI Radeon HD 4850 and newer):[5]
* Mac computer with an Intel processor (IA-32 'Yonah' processors such as Core Solo and Core Duo will only be able to run 32-bit applications; later x86-64 architecture processors such as Core 2 will also be able to run 64-bit applications)
* 1 GB of RAM
* 5 GB of free disk space
* DVD drive (also accessible via Remote Disc) or external USB or FireWire DVD drive for installation
Snow Leopard does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), all eMacs, plus pre-February 2006 Mac minis and the Power Mac G4 Cube), although PowerPC applications are supported via Rosetta, which is now an optional install.
Changes
Snow Leopard includes the following changes:
[edit] New features
* Boot Camp now allows Windows partitions to read and copy files from HFS+ partitions. The new version also adds support for advanced features on Cinema Displays and a new command-line version of the Startup Disk Control Panel.
* The Finder has been completely rewritten in 64-bit Cocoa to take advantage of the new technologies introduced in Snow Leopard. This has resulted in a much smaller OS footprint, taking up about 7 GB less space than Mac OS X v10.5 did. A smaller amount of recovered disk space (~250MB) has also been attributed to the fact that printer drivers are now downloaded or installed only as needed, rather than being all installed at once. The default install only contains those drivers needed for existing printers and a small subset of popular printers.[12]
* iChat enhancements include greater resolution video chats in iChat Theater and lowered upload bandwidth requirements.
* Microsoft Exchange support is now integrated into the Mail, Address Book, and iCal applications. However, only Microsoft Exchange 2007 is supported and customers using prior versions of Exchange must either upgrade or use Microsoft Entourage.
* Full multi-touch support has been added to notebooks prior to those introduced in October 2008. While the original MacBook Air and other early multi-touch enabled notebooks had support for some gestures, they were unable to use four-finger gestures. This limitation has now been removed in Snow Leopard.
* Preview now has artificial intelligence algorithms that allow it to infer the structure of a paragraph in a PDF document.
* QuickTime X, the next version of QuickTime player and multimedia framework, has been completely rewritten into a full 64-bit Cocoa application and builds on the media technologies in Mac OS X, such as Core Audio, Core Video, and Core Animation, to deliver playback. Apple has redesigned the QuickTime user interface to resemble the full-screen QuickTime view in prior versions, where the entire window displays the video and all controls including the title bar fade in and out as needed. QuickTime X also supports HTTP live streaming and takes advantage of ColorSync to provide high-quality color reproduction.[13] If Snow Leopard is installed on a Mac with an nVidia GeForce 9400M graphics card, QuickTime X will be able to use its video-decoding capabilities to reduce CPU load.
* Safari 4 features Top Sites, Cover Flow, VoiceOver, expanded standards support, and built-in crash resistance, which prevents browser crashes caused by plug-ins by running them in separate processes. Safari 4 is not new to Snow Leopard, as it is available for free in Mac OS X 10.4 (Tiger) and 10.5 (Leopard).
* Time Machine connection establishment and backups are now much faster.
* VoiceOver has also been greatly enhanced in Snow Leopard. Reading of web pages is improved with Auto Web Spots — areas of a page automatically designated for quick access. On newer Apple portables, trackpad gestures can be used to control many VoiceOver functions, including the 'rotor' gesture first seen in VoiceOver for the iPhone 3GS, allowing for the changing of certain VoiceOver navigation options by rotating fingers on the trackpad. Braille Display support is also improved, with Bluetooth displays supported for the first time.[14]
[edit] Refinements to the user interface
While the Finder was completely rewritten in 64-bit Cocoa, it has not received a major user interface overhaul. Instead, the interface has been slightly modified to allow better ease of use. These changes include:
* Exposé can now display all windows for a single program by left clicking and holding its icon in the dock. Windows are arranged in a new grid pattern.
* Contextual menus which come out of Dock icons now have more options and have a new look, with a semi-transparent charcoal background and white type.
* Stacks, when viewed as a grid, will now allow viewing of a subfolder without launching a separate Finder window. When viewed as grids and lists, it includes scroll-bars for folders with many files.[15]
* The default gamma has been changed from 1.8 to 2.2 to better serve the color needs of digital content producers and consumers.[12]
* Windows can now be minimized directly onto their application's icon in the dock.[16]
* Faster PDF and JPEG icon refreshes.[17]
* When searching for a network, the AirPort menu-bar animates until it finds a network and shows network strength in the drop down menu.
* Prefixes for bytes are now used in strictly decimal meaning (as opposed to their binary meaning) when describing disk space, such that an indicated file size of 1 MB corresponds to 1 million bytes, as commonly used by hard disk manufacturers.[18]
* Snow Leopard shuts down, wakes up, and goes to sleep faster. Depending on what computer is being tested, Snow Leopard can shut down in about 3 seconds.[citation needed]
[edit] New wallpapers
As with most upgrades of Mac OS, new wallpapers are available. There are new wallpapers in the Nature (two of which are of snow leopards), Plants and Black and White sub-folders under the Apple folder. Furthermore, there are new Apple wallpaper sub-folders with multiple wallpapers:
* Art: Dancer on the Stage, Nighthawks, Poppies Blooming, Sunday Afternoon, Suprematism, The Great Wave, and Water Lilies.
* Patterns: Pinstripe and Saree.
New solid colors can be used as wallpapers as well. There is a new blue and gray, as well as a solid kelp which serves as the 'green wallpaper'.
[edit] Dropped features
* It is no longer possible to change an application's language using the Finder 'Get Info' dialogue. While there are workarounds for some applications, others (such as Adobe After Effects) will not be able to be run in a different language than the one installed.
