Mac OS is the trademarked name for a series of graphical user interface-based operating systems developed by Apple Inc. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems. The Macintosh user experience is credited with popularizing the graphical user interface. The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.
Apple deliberately downplayed the existence of the operating system in the early years of the Macintosh to help make the machine appear more user-friendly and to distance it from other operating systems such as MS-DOS, which was more arcane and technically challenging. Much of this early system software was held in ROM, with updates typically provided free of charge by Apple dealers on floppy disk. As increasing disk storage capacity and performance gradually eliminated the need for fixing much of an advanced GUI operating system in ROM, Apple explored cloning while positioning major operating system upgrades as separate revenue-generating products, first with System 7.1 and System 7.5, then with Mac OS 7.6 in 1997.
Early versions of the Mac OS were compatible only with Motorola 68000-based Macintoshes. As Apple introduced computers with PowerPC hardware, the OS was upgraded to support this architecture as well. Mac OS 8.1 was the last version that could run on a 68000-class processor (the 68040). Mac OS X, which has superseded the "Classic" Mac OS, is compatible with both PowerPC and Intel processors through version 10.5 ("Leopard"). Version 10.6 ("Snow Leopard") supports only Intel processors.

Where does my money go?

To people and technology. Even though Wikipedia and its sister projects are one of the top five most-visited websites in the world, we employ fewer than 35 people; see our staff overview. Roughly half work on technology, a small team supports our public outreach and volunteer cultivation activities, and the remaining staff work in fundraising and administration. In addition, your support helps to pay for the technology infrastructure (servers and bandwidth) that keep Wikipedia running and growing.
Fundamentally, the Wikimedia Foundation exists to support and grow the enormous network of volunteers who write and edit Wikipedia and its sister projects -- more than 100,000 people around the world.

In computer networking, Server Message Block (SMB) operates as an application-layer network protocol mainly used to provide shared access to files, printers, serial ports, and miscellaneous communications between nodes on a network. It also provides an authenticated Inter-process communication mechanism. Most usage of SMB involves computers running Microsoft Windows, where it is often known as "Microsoft Windows Network".
When discussing SMB, one should distinguish:

• the SMB protocol specification
• the "server" and "workstation" services that implement the protocol on Windows
• the Samba service that implements the protocol on Unix systems
• NetBIOS transport used by SMB on legacy versions of Windows
• the DCE/RPC services that use SMB as an authenticated Inter-process communication channel (over named pipes)
• the "Network Neighborhood" protocols which primarily (but not exclusively) run as datagram services directly on the NetBIOS transport
