    • 2Mac OSIntroduction: Mac OS is a series of graphical user interface-based operating systems developed byApple Inc. for their Macintosh line of computer systems. Formerly Apple Inc. was called AppleComputer, Inc. The Macintosh user experience is credited with popularizing the graphical userinterface. The Macintosh or Mac is a series of several lines of personal computers designed,developed, and marketed by Apple Inc. The first Macintosh was introduced by Apples thenChairman Steve Jobs on January 24, 1984; it was the first commercially successful personalcomputer to feature a mouse and a graphical user interface rather than a command-line interface. The original form of what Apple would later name the "Mac OS" was the integral andunnamed system software first introduced in 1984 with the original Macintosh, usually referredto simply as the System software. The company continued to have success through the secondhalf of the 1980s, only to see it dissipate/disperse in the 1990s as the personal computer marketshifted toward the "Wintel" platform: IBM PC compatible machines running MS-DOS andMicrosoft Windows. Years later, Apple consolidated its multiple consumer-level desktop models into the 1998iMac all-in-one. This proved to be a sales success and saw the Macintosh brand revitalized,albeit not to the market share level it once had. Current Mac systems are mainly targeted at thehome, education, and creative professional markets. These include the descendants of theoriginal iMac and the entry-level Mac mini desktop models, the Mac Pro tower graphicsworkstation, the MacBook, MacBook Air and MacBook Pro laptops.
    • 3Mac OSConception: Apple from the beginning deliberately sought to as minimize by design the usersconceptual awareness of the operating system. Tasks that on other products required a moreexplicit working knowledge of an operating system would on a Macintosh be accomplished byintuitive mouse gestures and manipulation of graphical control panels. The intention was that theproduct would thus be more user-friendly and so more easily mastered. This would differentiateit from devices using other operating environments, such as MS-DOS machines, which weremore technically challenging to operate. The core of the system software was held in ROM, with updates (which would overrideROM-resident portions in RAM) typically provided free of charge by Apple dealers on floppydisk. The users involvement in an upgrade of the operating system was also minimized torunning an installer, or simply replacing system files, the simplicity of which again differentiatedthe product from other offerings.History of Mac OS: On January 24, 1984, Apple Computer Inc. (now Apple Inc.) introduced the Macintoshpersonal computer, with the Macintosh 128K model, which came bundled with what was laterrenamed the Mac OS, but then known simply as the System Software. The Macintosh is oftencredited with popularizing the graphical user interface. The Mac OS has been pre-installed onalmost every Macintosh computer sold. The operating system is also sold separately on the MacApp Store for $29.99. It is also sold on a USB flash drive for $69.00. (Mac OS X Lion only.)The original Macintosh system software was partially based on the Lisa OS, previously releasedby Apple for the Lisa computer in 1983 and, as part of an agreement allowing Xerox to buyshares in Apple at a favorable rate; it also used concepts from the Xerox PARC Xerox Alto,which Steve Jobs and several other Macintosh team members had previewed. The Macintosh project started in early 1979 with Jef Raskin, who envisioned an easy-to-use, low-cost computer for the average consumer. In January 1981, Steve Jobs completely tookover the Macintosh project. Jobs and a number of Apple engineers visited Xerox PARC in
    • 4Mac OSDecember 1979, three months after the Lisa and Macintosh projects had begun. After hearingabout the pioneering GUI technology being developed at Xerox PARC from former Xeroxemployees like Raskin, Jobs negotiated a visit to see the Xerox Alto computer and Smalltalkdevelopment tools in exchange for Apple stock options. The final Lisa and Macintosh operatingsystems mostly used concepts from the Xerox Alto, but many elements of the graphical userinterface were created by Apple including the menu bar, pop-up menus and the concepts of dragand drop and direct manipulation. Unlike the IBM PC, which used 8 kB of system ROM for power-on self-test (POST) andbasic input/output system (BIOS), the Mac ROM was significantly larger (64 kB) and held keyOS code. Much of the original Mac ROM was coded by Andy Hertzfeld, a member of theoriginal Macintosh team. He was able to conserve some of the precious ROM space byinterleaving some of the assembly language code. In addition to coding the ROM, he also codedthe kernel, the Macintosh Toolbox and some of the desktop accessories (DAs) as well. The iconsof the operating system, which represented folders and application software, were designed bySusan Kare, who later designed the icons for Microsoft Windows 3.0. Bruce Horn and SteveCapps wrote the Macintosh Finder as well as a number of Macintosh system utilities. The first version of the Mac OS (simply called System) is easily distinguished betweenother operating systems from the same period because it does not use a command line interface;it was one of the first operating systems to use an entirely graphical user interface or GUI.Additional to the system kernel is the Finder, an application used for file management, whichalso displays the Desktop. The two files were contained in a folder directory labeled SystemFolder, which contained other resource files, like a printer driver, needed to interact with theSystem.
    • 5Mac OSTypes of Mac OS:Mac OS can be divided into two families: 1. The Mac OS Classic family, which was based on Apples own code 2. The Mac OS X operating system, developed from Mac OS Classic family, and NeXTSTEP, which was UNIX-based.Mac OS Classic: Mac OS Classic is a series of operating systems based on Apples own code and graphicaluser interfaces developed, marketed, and sold by Apple Inc. Since 1984, Mac OS has beenincluded with all new Macintosh computer systems. The final release of the "classic" Mac OS,which had been Apples primary operating system in 1999. The "classic" Mac OS is characterized by its total lack of a command line; it is acompletely graphical operating system. Versions of Mac OS up through System 4 only ran oneapplication at a time. Even so, it was noted for its ease of use. Mac OS gained cooperativemultitasking with System 5, which ran on the Mac SE and Macintosh II. It was criticized for itsvery limited memory management, lack of protected memory, and susceptibility to conflictsamong operating system "extensions" that provide additional functionality (such as networking)or support for a particular device. Some extensions may not work properly together, or workonly when loaded in a particular order. Troubleshooting Mac OS extensions could be a time-consuming process of trial and error. The Macintosh originally used the Macintosh File System (MFS), a flat file system withonly one level of folders. This was quickly replaced in 1985 by the Hierarchical File System(HFS), which had a true directory tree. Both file systems are otherwise compatible.

    • 7Mac OS 7. System 7 8. Mac OS 7.6 9. Mac OS 8 10. Mac OS 9Mac OS X: Mac OS X is the newest of Apple Inc.s Mac OS line of operating systems. Although it isofficially designated as simply "version 10" of the Mac OS, it has a history largely independentof the earlier Mac OS releases. Mac OS X is a series of Unix-based operating systems and graphical user interfacesdeveloped, marketed, and sold by Apple Inc. Since 2002, Mac OS X has been included with allnew Macintosh computer systems. It is the successor to Mac OS 9, released in 1999; the finalrelease of the "classic" Mac OS, which had been Apples primary operating system since 1984. Mac OS X, whose X is the Roman numeral for 10 and is a prominent part of its brandidentity, is a Unix-based graphical operating system, built on technologies developed at NeXTbetween the second half of the 1980s and Apples purchase of the company in late 1996. From itssixth release, Mac OS X v10.5 "Leopard" and onward, every release of Mac OS X gained UNIX03 certification while running on Intel processors. Mac OS X also makes use of the BSD codebase. Mac OS X is also the basis for iOS, (previously iPhone OS) used on Apples iPhone, iPodTouch, and iPad.
    • 8Mac OSFeatures of Mac OS X1.Aqua The graphical user interface of Mac OS X is called Aqua. This includes the look andfeel, behavior, and integration of GUI elements. The GUI application environments of Mac OSX, Carbon, Cocoa, and Java, all support Aqua. Classic does not, and Mac OS 9 applicationsrunning under Classic look like they did on Mac OS 9.2.Data and Information Management Mac OS X makes a very good attempt at keeping various data and informationorganized by context, rather than having files strewn all over the place.3.Devices Apple has excellent support for FireWire devices.4.Power Management Mac OS X in conjunction with Macintosh hardware make up for some impressivepower and thermal management.5.Security Mac OS X includes various security features, services, and APIs (including whatsavailable on typical *nix systems), such as those for controlling/managing passwords,certificates, public/private keys, application-level privileged operations (capabilities), trustpolicies, etc. Mac OS X supports Kerberos, OpenSSL, and PAM as well.6.Speech Interface Mac OS X includes both speech recognition (part of Carbon) and synthesis frameworks.

    • 10Mac OSDifference between Mac OS and Windows : Mac operating system is based on Unix while Windows operating system is based on DOS programming language. Mac is more secure than windows as windows can be easily hacked since it is used universally. Mac is focused on graphics and multimedia functions while windows is focused on office function. MAc dont have a big desktop unit instead only have a monitor whereas in windows there is a big desktop unit. Close and minimize boxes are in the top left corners of the monitor in Mac while it is on top right corners of the monitor in windows.Difference between Mac OS and Linux : Mac is an entire platform consisting of software and hardware while Linux is just an operating system consisting of only software. Mac is focused on graphics and multimedia functions while Linux is focused on office functions. Mac cannot be installed on all the computers whereas Linux is an operating system that can be installed on any computer.
