Editing Mac OS X Tiger (section)

===End-user features===
Apple advertised that Mac OS X 10.4 Tiger had over 150 new and improved features, including:
* '''[[Spotlight (software)|Spotlight]]''' — Spotlight is a full-text and [[metadata (computing)|metadata]] search engine that can search everything on one's Mac, including [[Microsoft Word]] documents, [[iCal]] calendars and [[Address Book (Mac OS X)|Address Book]] contact cards. The feature is also used to build the concept of '[[virtual folder|smart folders]]' into the [[Macintosh Finder|Finder]]. Spotlight will index files as they are saved, so they can be quickly and easily found through a search-as-you-type box in the menu bar. As a side-effect, it adds hidden folders and indexing files to removable media like USB flash drives.
* '''[[iChat|iChat AV]]''' — The new iChat AV 3.0 in Mac OS X 10.4 Tiger supports up to four participants in a video conference and ten participants in an audio conference. It also now supports communication using the [[Extensible Messaging and Presence Protocol|XMPP]] protocol. An XMPP server called [[iChat Server]] is included on Mac OS X 10.4 Tiger Server.
* '''Safari RSS''' — The new Safari 2.0 [[web browser]] in Mac OS X 10.4 Tiger featured a built-in reader for [[RSS (file format)|RSS]] and [[Atom (standard)|Atom]] [[web syndication]] that can be accessed easily from an RSS button in the address bar of the web browser window. An updated version of Safari, included as part of the free Mac OS X 10.4.3 Tiger update, can also pass the [[Acid2]] web standards test.
* '''[[Mail (OS X)|Mail 2]]''' — The new version of Mail.app [[email client]] included in Mac OS X 10.4 Tiger featured an updated interface, "Smart Mailboxes", which utilizes the Spotlight search system, parental controls, as well as several other features.
* '''[[Automator (software)|Automator]]''' — A scripting tool to link applications together to form complex automated workflows (written in [[AppleScript]], [[Cocoa (software)|Cocoa]], or both). Automator came with a complete library of actions for several applications that can be used together to make a Workflow.
* '''[[VoiceOver]]''' — screen reader interface similar to Jaws for Windows and other Windows screen readers that offers the blind and visually impaired user keyboard control and spoken [[English language|English]] descriptions of what is happening on screen. VoiceOver enables users with visual impairment to use applications via keyboard commands. VoiceOver is capable of reading aloud the contents of files including web pages, mail messages and word processing files. Complete keyboard navigation lets the user control the computer with the keyboard rather than the mouse, a menu is displayed in a window showing all the available keyboard commands that can be used.
* '''A complete built-in Dictionary/Thesaurus''' based on the [[New Oxford American Dictionary|New Oxford American Dictionary, Second Edition]], accessible through an application, Dictionary, a Dashboard widget, and as a system-wide command (see below).
* '''[[.Mac]] syncing''' — Though this was not a new feature, .Mac syncing in Tiger is much improved over Panther. Syncing tasks in Tiger are now accomplished through the .Mac system preferences pane rather than the [[iSync]] application.
* '''[[QuickTime]] 7''' — A new version of Apple's multimedia software has support for the new [[H.264|H.264/AVC]] codec, which offers better quality and scalability than other [[video codec]]s. {{Citation needed|date=February 2010}} This new codec is used by iChat AV for clearer video conferencing. New classes within Cocoa provide full access to QuickTime for Cocoa application developers. The new QuickTime 7 player application bundled with Tiger now includes more advanced audio and video controls as well as a more detailed Information dialog, and the new player has been rebuilt using Apple's [[Cocoa (API)|Cocoa API]] to take advantage of the new technologies more easily.
* '''New [[Unix]] features''' — New versions of [[cp (Unix)|cp]], [[mv (Unix)|mv]], and [[rsync]] that support files with [[resource fork]]s. Command-line support for features such as the above-mentioned Spotlight is also included.
* '''[[Xcode|Xcode 2.0]]''' — Xcode 2.0, Apple's Cocoa development tool now includes visual modelling, an integrated Apple Reference Library and graphical remote [[debugging]].
