MAC OS X
Mac OS X is the name of Apple's desktop operating system. Its features include:
Aqua GUI — Apple's graphical user interface is a highly-iterated facet of the operating system, designed to be a tactile, intuitive and highly-responsive user experience.
Automator — A system utility for automating tasks in the organizational context of a workflow. Added in version 10.4.
Dashboard — A workspace of configurable widgets including sticky notes, news tickers, weather apps, and a standard and scientific calculator. Widgets are arranged on a customizable workspace overlay which can be toggled with a keystroke. Added in version 10.4.
Mission Control — In OS X, every window is a GL object subjugate to larger operating system GUI. Each window can be viewed in realtime as an icon, and the Mission Control interface allows users to quickly navigate and control running applications across multiple virtual desktops. First introduced in summer of 2003, formerly known as Exposé.
FileVault — Provides control of disk encryption, vital in corporate settings. Added in version 10.3.
Screen Sharing — When enabled, allows remote users to view or control the machine. Compatible with standard VNC clients. Added in version 10.5.
Time Machine — Automated file backup service with chronological revision control and a highly-developed visualized metaphor. When using Time Machine to view the history of your backups, the folders and files scroll forward and backward through time like a circular card file or rolodex. Added in version 10.5.
SAD MAC ERRORS
If the "happy Macintosh" and the "Welcome to Macintosh" screens appear before the "sad Macintosh", the problem is probably in the system software.
When the "sad Macintosh" face appears immediately at power up, it usually means a hardware problem. Some of the common hardware issues are problems with SIMMs or hard drive.
