The Macintosh, or Mac, is a series of several lines of personal computers, manufactured by Apple Inc. The first Macintosh was introduced on January 24, 1984, by Steve Jobs and it was the first commercially successful personal computer to feature two known, but still unpopular features—the mouse and the graphical user interface, rather than the command-line interface of its predecessors.

Production of the Mac is based on a vertical integration model in that Apple facilitates all aspects of its hardware and creates its own operating system (called System Software, later renamed to Mac OS, see the lower image) that is pre-installed on all Mac computers. This is in contrast to most IBM PC compatibles, where multiple sellers create hardware intended to run another company’s operating software. Apple exclusively produces Mac hardware, choosing internal systems, designs, and prices. Apple also develops the operating system for the Mac. The modern Mac, like other personal computers, is capable of running alternative operating systems such as Linux, FreeBSD, and, in the case of Intel-based Macs, Microsoft Windows. However, Apple does not license Mac OS X for use on non-Apple computers.

The Beginning of Macintosh Computers

The Macintosh project started in the late 1970s with Jef Raskin (1943–2005) (see the nearby image), an Apple employee, who envisioned an easy-to-use, low-cost computer for the average consumer. He wanted to name the computer after his favorite type of apple, the McIntosh, but the name had to be changed for legal reasons. In September 1979, Raskin was authorized by the management to start hiring for the project, and he began to look for an engineer who could put together a prototype. Bill Atkinson, a member of Apple’s Lisa team (which was developing a similar but higher-end computer), introduced him to Burrell Smith, a service technician who had been hired earlier that year. Over the years, Raskin assembled a large development team that designed and built the original Macintosh hardware and software; besides Raskin, Atkinson and Smith, the team included Chris Espinosa, Joanna Hoffman, George Crow, Bruce Horn, Jerry Manock, Susan Kare, Andy Hertzfeld, and Daniel Kottke.

Original Macintosh Specifications

The first Macintosh board, designed by Burrell Smith, had 64 kilobytes (KB) of RAM, used the Motorola 6809E microprocessor, and was capable of supporting a 256×256 pixel black-and-white bitmap display. Bud Tribble, a Macintosh programmer, was interested in running the Lisa’s graphical programs on the Macintosh, and asked Smith whether he could incorporate the Lisa’s Motorola 68000 microprocessor into the Mac while still keeping the production cost down. By December 1980, Smith had succeeded in designing a board that not only used the 68000, but bumped its speed from 5 to 8 megahertz (MHz); this board also had the capacity to support a 384×256 pixel display.

Smith’s design used fewer RAM chips than the Lisa, which made production of the board significantly more cost-efficient. The final Mac design was self-contained and had the complete QuickDraw picture language and interpreter in 64 Kb of ROM and 128 KB of RAM. Though there were no memory slots, its RAM was expandable to 512 KB by means of soldering sixteen chip sockets to accept 256 Kb RAM chips in place of the factory-installed chips. The final product’s screen was a 9-inch, 512×342 pixel monochrome display, exceeding the prototypes.

The Macintosh Catches Steve Jobs’ Attention

The design caught the attention of Steve Jobs, co-founder of Apple. Realizing that the Macintosh was more marketable than the Lisa, he began to focus his attention on the project. Raskin finally left the Macintosh project in 1981 over a personality conflict with Jobs, and the final Macintosh design is said to be closer to Jobs’ ideas than Raskin’s. After hearing of the pioneering GUI technology being developed at Xerox PARC, Jobs had negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. The Lisa and Macintosh user interfaces were partially influenced by technology seen at Xerox PARC and were combined with the Macintosh group’s own ideas.

The Macintosh 128k (see the lower image) was announced to the press in October 1983 and was introduced in January 1984. It came bundled with two applications designed to show off its interface: MacWrite and MacPaint. Although the Mac garnered an immediate, enthusiastic following, some labeled it a mere “toy.” Because the machine was entirely designed around the GUI, existing text-mode and command-driven applications had to be redesigned and the programming code rewritten; this was a time consuming task that many software developers chose not to undertake, and resulted in an initial lack of software for the new system. In April 1984 Microsoft’s MultiPlan migrated over from MS-DOS, followed by Microsoft Word in January 1985. In 1985, Lotus Software introduced Lotus Jazz after the success of Lotus 1-2-3 for the IBM PC, although it was largely a flop. Apple introduced Macintosh Office the same year with the still-famous “lemmings” ad.

Marketing the first Macintosh

For a special post-election edition of Newsweek in November 1984, Apple spent more than $2.5 million to buy all 39 of the advertising pages in the issue. Apple also ran a “Test Drive a Macintosh” promotion, in which potential buyers with a credit card could take home a Macintosh for 24 hours and return it to a dealer afterwards. While 200000 people participated, dealers disliked the promotion, the supply of computers was insufficient for demand, and many were returned in such a bad shape that they could no longer be sold. This marketing campaign caused CEO John Sculley to raise the price from $1995 to $2495.

In 1985, the combination of the Mac, Apple’s LaserWriter printer, and Mac-specific software like Boston Software’s MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphics, it was an activity to become known as desktop publishing. Initially, desktop publishing was unique to the Macintosh, but eventually became available for IBM PC users as well. Later, applications such as Macromedia FreeHand, QuarkXPress, Adobe Photoshop, and Adobe Illustrator strengthened the Mac’s position as a graphics computer and helped to expand the emerging desktop publishing market.

The limitations of the first Mac soon became clear: it had very little memory, even compared with other personal computers in 1984, and could not be expanded easily; and it lacked a hard disk drive or the means to attach one easily. In October 1985, Apple increased the Mac’s memory to 512 KB, but it was inconvenient and difficult to expand the memory of a 128 KB Mac. In an attempt to improve connectivity, Apple released the Macintosh Plus on January 10, 1986 for $2600. It offered one megabyte of RAM, expandable to four, and a then-revolutionary SCSI parallel interface, allowing up to seven peripherals—such as hard drives and scanners—to be attached to the machine. Its floppy drive was increased to an 800 KB capacity. The Mac Plus was an immediate success and remained in production, unchanged, until October 15, 1990; on sale for just over four years and ten months, it was the longest-lived Macintosh in Apple’s history.

At its introduction, the Macintosh was targeted for two primary markets: knowledge-workers and students. Referring to the telephone as the first desktop appliance, Steve Jobs hoped that the Macintosh would become the second desktop appliance. As Bill Gates stated, To create a new standard takes something that’s not just a little bit different. It takes something that’s really new, and captures people’s imaginations. Macintosh meets that standard.

Through the second half of the 1980s, the company built market share only to see it dissipate in the 1990s as the personal computer market shifted towards IBM PC compatible machines running MS-DOS and Microsoft Windows.

Ask a Mac OS X fan or a Windows fan what the difference is between the two operating systems, and the short answer might be something like, 'The difference is, the one I use doesn't stink.' That response may underscore the emotional pull an operating system has with a particular sort of computer user, but it is not very helpful for getting at the heart of the matter. The long answer involves understanding the soul of each OS.

Mac OS X is gaining favor among a growing number computer users. What is it that makes up the real difference between OS X and Windows? The long answer goes well beyond the Dock, the Start Button, or other obvious surface features and appearance details that any user can easily see at first glance.

'Apple is second to none in user experience,' Bill Gribbons told MacNewsWorld. Gribbons is director of the Master of Science in Human Factors in Information Design at Bentley University and senior consultant to the Bentley University Design and Usability Center. 'They turned it into an art form. Apple's approach to product design is what distinguishes them from Microsoft. Microsoft is not always focused on technology. It is not always a good experience for users and is not always easy to learn. It does not always fit the users' needs.'

Close Birth

Certainly, both Microsoft's and Apple's operating systems have changed dramatically over the years.

The two systems share a common lineage, of sorts. Windows was released in 1985 and was at least inspired (if not copied) from the earliest Mac OS, which Microsoft had access to as a Mac software developer. Apple actually sued Microsoft in the 1980s for 'borrowing' their ideas, according to Edward Shepard, marketing manager of Apple sales professional for Small Dog Electronics.

'Forward 25 years, and it can be argued that Microsoft borrowed many ideas for Vista's look and feel from Mac OS X. Likewise, Apple has also borrowed ideas from Windows over the years. The two OSes are like two competitive, wealthy cousins from different sides of a single family tree,' Shepard told MacNewsWorld.

From these entwined origins, the two systems embarked on different paths and gathered families of followers either born into the fold or converted to it. For instance, Apple has emphasized the seamless integration of software and hardware, as well as a core focus on graphical feedback. Windows was designed as a licensed product to run on thousands of different computer models produced by dozens of companies around the world, according to Shepard.

Soul Differences

Apple's approach made it easier for developers to assure compatibly and reliability. However, it has also limited the size of Apple's user base, which stood at about 30 million users in early 2008, Shepard noted.

Meanwhile, Microsoft emphasized getting as large a user base as possible for Windows. Now, somewhere around 90 percent of computer users run Windows. On a global scale, having a dominant OS probably helped facilitate mass adoption of personal computers. On the other hand, it also made Windows an attractive and easy target for viruses, Trojans, worms, and other computer attacks, he added.

These two paths followed distinctively different design passions, and it's in the design that the essence of their souls emerge.

Mac OS X has a restrained, coolly calculating soul that effectively handles its business, though perhaps doesn't always tell you about everything on its mind. As a human, Mac OS X would be an efficient, dedicated concierge that smoothly does his job, albeit with an air of quiet superiority. Windows has an aggressive, do-it-all soul, but often huffs and puffs to remind you it's working hard (even if it's for your benefit). As a human, Windows would be a sweaty middle manager stomping around the office, reliable enough and 'surprisingly good at karaoke,' quipped Shepard.

Designed Distinctions

Peeling back the trappings of each OS unveils a closer glimpse at the architectural differences that separate Mac and Windows systems. At the root of the architecture lies the core programming.

'Windows was built around networking. Its foundation is on highly modifiable DLLs (Dynamic Link Libraries) to support many applications and a registry file for multiple configurations. On the Mac side, the OS is based on Unix, Mach and the Apple OS structure,' Gene Spafford, professor in the department of computer sciences at Purdue University, told MacNewsWorld.

Mach is an operating system microkernel Carnegie Mellon University developed to support operating system research. The basis of the Mac OS X is still the core built by Carnegie Mellon.

Architectural Adversaries

Windows' design set led to the growth of an OS that was full of tweeks. The Windows of today evolved from the NT/Windows 2000 structure. It facilitated drag-and-drop convenience and easy-to-install applications, Spafford explained. In contrast, the Mac OS seldom put in a shared library to install applications.

Instead, the Mac uses permissions like Unix. No large-scale system management is needed. The result: When something installs on an Apple computer, the user knows it. The installation cannot happen silently.

Another difference is that most configuration settings on the Mac are in plain text. There is no arcane registry setting like in Windows, and the kernel stays minimal.

'This is the overall Mac philosophy of how things get added in. Microsoft extended the design to add to the kernel,' Spafford said.

Growth Spurts

Both the Mac and Windows operating systems are inherently different today than their earlier generations. Apple had a shift in technology that brought an end to the single-threaded OS that was similar to DOS (Disk Operating System), according to Spafford. Windows designers began peeling away the DOS core upon which the Windows GUI (graphical user interface) was applied with the migration to Windows XP.

Similarly, Mac OS 9 was creaking under the load. Steve Jobs, who at this point had returned to head up Apple once again, changed the operating system to make the OS X into a new design, explained Spafford.

'What was novel was its ability to seamlessly emulate OS 9 running under OS X, much like VMware functions today. This enabled users to switch over without losing their software. The new version strengthened Unix as the underlying kernel,' he said.

Sensitivity Training

One of the main aspects of the Mac soul is the connection its designers have with Mac users. Gribbons, who specializes in studying how people interact with systems, describes Mac developers as having a deep, intimate understanding of what people want and value.

'Apple maps the system design to whatever product they do to that model. Apple always feels like a user's best friend,' said Gribbons.

With Apple, users enjoy a carefully orchestrated experience that is not accidental. From the way it is marketed, sold, packaged and supported, it is designed to be seamless.

'You don't see that from Microsoft,' he said.

How Good Is Too Good?

However, this approach almost brought doom to Apple, noted Gribbons. At one point, the company almost went out of business because of it, he said.

'The systems didn't seem serious. They were expensive. There were delays in getting to the market. They wanted to get it perfect, but the market didn't demand this. On the other hand, Microsoft got its products to the market more quickly, and they were good enough. This is how Microsoft captured the market share,' Gribbons said.

Addressing this conundrum was part of the soul searching that Mac developers did to salvage the Mac OS from itself. For much of the 1990s and up until about the last five years, the product was almost too good, he explained. Consumers were really buying too much product, and the price point was way above that of Windows-based products.

What's the Diff?

Differences abound in the two systems, but both can do essentially the same things, according to Fernando Machado, who has a decade of experience running a computer maintenance and service business and is a computer expert on JustAnswer.com.

'Windows is better for gaming due to the large amount of games that are available for it. Mac, however, has better overall security and is less prone to attackers,' he told MacNewsWorld.

The differences in OS design reflect a clear distinction in what attracts the user base. For instance, the Mac is designed more for graphical and multimedia functions and tends to run better than Windows doing so. Windows, however, is much better with statistical applications as well as office applications. It also seems that Windows is easier for the user to customize, Machado explained.

The Roots of Design

Windows is designed to be a do-it-all-at-any cost OS, which has its benefits and complications, Shepard added. For example, there are six versions of Windows Vista, and there will be six versions of Windows 7, all listed at different prices. In contrast, Apple simply sells one fully loaded version of OS X for one price (US$129). This version even includes Boot Camp for installing Windows on a Mac if desired.

'The biggest difference between the two goes back to their origins. Windows tries to be everything to everyone, is phenomenally successful, but has a history of security vulnerabilities, peripheral incompatibilities (ironically enough), and upgrade confusion. Apple still has a more restrained consumer focus, still controls the design and engineering of its hardware and software, competes hard in some demographics but is content letting others go. Thus, it has a smaller user base,' Shepard summarized.

All things considered, the two OSes are starting to become quite similar, according to Mike Palumbo, an IT specialist for the Center for Instructional Technology at Eastern Connecticut State University.

Most OS preference these days is driven by the same brand loyalty that divides Ford and Chevy owners and Coke and Pepsi drinkers, he said -- and the arguments that ensue are often the equivalent of 'Tastes Great! vs. Less Filling!'

Soul Survivors

In recent years, both companies have learned from each other and incorporated each other's ideas. Windows has become more user friendly and more slick in its design, while Apple has included functional features and control options that were previously unavailable, according to Palumbo.

'Apple makes a lot of assumptions about what you want control over and makes a lot of decisions for you, and that's great for the majority of the users. Windows gives the user more control and more options, and by virtue of that, more opportunity to mess it up,' Palumbo told MacNewsWorld.

Windows designers are catering to an audience that likes to look under the hood and shift manually. The average user can still drive it, but the enthusiast can really tweak it if they desire, he explained. Windows designers have made it possible for IT pros to completely control every aspect of how the computer is used by the employee.

'Apple designs its interface and even the outward hardware to appeal for people who appreciate design. It's slick, shiny and expensive, not unlike buying a sports car,' said Palumbo.
