Macintosh Operating System
When Apple Computer developed the Macintosh computer system, they also strove to develop an operating system for this new machine. They didn抰 want to rely on the competitor抯 MS-DOS system which was developed by Microsoft Corporation. So programmers at Apple set out to make an operating system exclusively for the Macintosh computer.
What they came up with was Mac OS (standing for Mac Operating System) which introduced the new graphical user interface (GUI) that would serve as a model for other operating systems. In the early years of the Macintosh, Apple would downplay the existence of the operating system to make it appear user-friendly and to distance it from the MS-DOS system being used over at Microsoft.
Like Windows, the Macintosh operating system has undergone a series of changes making it more efficient as well as more user-friendly. Originally, the biggest advantage of Mac OS was the lack of a command line entry as was required by MS-DOS. However, it wasn抰 without its own problems.
Critics of the Mac OS cited its limited memory management,[link widoczny dla zalogowanych], lack of protected memory,[link widoczny dla zalogowanych], and susceptibility to conflicts on a network. This last one was especially problematic because certain extensions could provide additional functionality among devices. Some of the extensions would not work properly together or they would only work when loaded in a particular order.
The truth is, however,[link widoczny dla zalogowanych], that the Macintosh operating system offered � and still offers people advancements that have since been used as a basis for other operating systems being developed. These advantages include:
* Color Sync which matches colors on the screen with colors on a printer
* The Finder which allows the user to browse the file system and launch applications
* Plain Talk that is a speech synthesis program allowing the spoken word to control functions on the computer
* Quick Draw that makes it easy to make images on the personal computer
* Quick Time which supports audio-visual editing and playback of multi-media content over a network
* True Type which is a font technology that shows a font on the screen that will print exactly the way it looks
The Macintosh operating system isn抰 as popular commercially as Windows, but it is still the preferred system for Mac owners. It has proven to be the foundation for much of what we see on computers today. Without the Macintosh operating system, we wouldn抰 have the types of operating system that we have now.

He should, of course, have told the parents immediately, ideally by telephone followed by a letter, of their right to make representations to the governing body.
