Introduction : 

Mac OS is a series of graphical user interface-based operating systems developed by Apple Inc. for their Macintosh line of computer systems. Introduction

Slide 4: 

Graphical User Interface. Mac OS was the integral and unnamed system software first introduced in 1984 with the original Macintosh

Concept : 

Minimize Awareness !!! Tasks require more explicit working knowledge of an operating system but on Macintosh it is accomplished by intuitive mouse gestures and manipulation of graphical control panels. Concept

Slide 7: 

The core of the system software was held in ROM. The user's involvement in an upgrade of the operating system was also minimized to running an installer.

History of Mac OS : 

The Macintosh project started in early 1979 with Jef Raskin. The original Macintosh system software was partially based on the Lisa OS. Also used concepts from the Xerox PARC, Xerox Alto. History of Mac OS

Slide 9: 

Steve Jobs and a number of Apple engineers visited Xerox PARC in December 1979. In January 1981, Steve Jobs completely took over the Macintosh project.

Slide 10: 

The final Lisa and Macintosh operating systems mostly used concepts from the Xerox Alto. Many elements of the graphical user interface were created by Apple. Unlike the IBM PC, which used 8 kB of system ROM for power-on self-test (POST) and basic input/output system (BIOS), the Mac ROM was significantly larger (64 kB ) and held key OS code.

Slide 11: 

Xerox Alto – the first computer to use the desktop & GUI

Slide 12: 

Andy Hertzfeld, a member of the original Macintosh team coded original Mac ROM. In addition to coding the ROM, he also coded the Macintosh Toolbox and some of the desktop accessoriesa(DAs). The icons of the operating system, which represented folders and application software were designed by Susan Kare. Bruce Horn and Steve Capps wrote the Macintosh Finder and number of Macintosh system utilities.

TYPES : 

Mac OS can be divided into two families: Mac OS Classic , which was based on Apple's own code. Mac OS X , developed from Mac OS Classic and NeXTSTEP, which was UNIX-based. TYPES

Mac OS Classic : 

Mac OS Classic is a series of operating systems based on Apple's own code and graphical user interfaces developed, marketed, and sold by Apple Inc. Since 1984, Mac OS has been included with all new Macintosh computer systems. The final release of the classic Mac OS, which had been Apple's primary operating system was in 1999. Mac OS Classic

Slide 15: 

The Mac OS classic is characterized by its total lack of a command line. Versions of Mac OS up through System 4 only ran one application at a time. Mac OS gained cooperative multitasking with System 5, which ran on the Mac SE and Macintosh II.

Slide 16: 

The Macintosh originally used the Macintosh File System (MFS), a flat file system with only one level of folders. This was quickly replaced by the Hierarchical File System (HFS) in 1985 , which had a true directory tree

Release of Mac OS Classic : 

There has been ten significant releases of the namely: System 1 System 2 System 3 System 4 System 5 System 6 System 7 Mac OS 7.6 Mac OS 8 Mac OS 9 Release of Mac OS Classic

Mac OS X : 

Mac OS X is the newest of Apple Inc.'s Mac OS line of operating systems. Although it is officially designated as simply "version 10" of the Mac OS, it has a history largely independent of the earlier Mac OS releases. Mac OS X is a series of Unix-based operating system and graphical user interfaces developed, marketed, and sold by Apple Inc. Mac OS X

Slide 20: 

Since 2002, Mac OS X has been included with all new Macintosh computer systems. It is the successor to Mac OS 9, released in 1999. Mac OS X, where X is the Roman numeral for 10. Mac OS X is also the basis for iOS, (previously iPhone OS) used on Apple's iPhone, iPod Touch, and iPad.

Slide 21: 

Releases of Mac OS X are named after big cats. for example, Mac OS X v10.7 is usually referred to by Apple and users as "Lion".

Release of Mac OS X : 

There have been eight significant releases of the client version namely: Mac OS X v10.0 (Cheetah) Mac OS X v10.1 (Puma) Mac OS X v10.2 (Jaguar) Mac OS X v10.3 (Panther) Mac OS X v10.4 (Tiger) Mac OS X v10.5 (Leopard) Mac OS X v10.6 (Snow Leopard) Mac OS X v10.7 (Lion) Release of Mac OS X

Difference 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. Difference between Mac OS and Windows

Slide 26: 

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. Difference between Mac OS and Linux
