Aqua contains extensive use of colour and texture as well as extremely detailed icons. It provides good visual features as well as the tools to customize the user interface as per the user requirements. User InterfaceĪqua is the user interface of Mac OS X. The Java applications and Java applets can be run using the Java environment. The cocoa applications use the benefits of the Mac OS X Structure the most. The cocoa environment provides object-oriented application development environment. This is called carbonising the application. The carbon environment is used to port existing applications to carbon application program interfaces. The classic environment makes sure that applications written for the previous versions of the operating system can run smoothly. Carbon, Cocoa and Java are the three application development environments available. The application subsystem in Mac OS X provides the classic environment to run classic applications.

It also enables creative applications such as iMovie, iTunes etc. QuickTime is used for different digital media such as digital video, audio and video streaming etc.

It is also used in Unix and Windows systems. OpenGL provides support for 3-D graphics in the system such as texture mapping, transparency, antialiasing, atmospheric effects, special effects etc. It provides fonts, interface graphics, rendering of the images etc. The 2-D graphics in the graphics subsystem is managed by Quartz. The graphics subsystem in the Mac OS X contains three parts i.e. It also provides I/O services for Mac OS X and supports plug-and-play, hot-swapping and power management. Some of the major features of the Darwin core are protected memory, automatic memory management, preemptive multitasking, advanced virtual memory etc. Different versions of Darwin can be used to enhance the Mac OS X. anyone can obtain its source code and make modifications to it. Mach is the main part of the Darwin core and it performs operations such as memory use, data flow from and to CPU etc. The Darwin Core is based on the BSD (Berkeley Software Distribution) version of Unix. The top layer is Aqua, which is the user interface.Ī diagram that demonstrates the structure of Mac OS X is as follows −ĭetails about the different components of the Mac OS X structure as seen in the image above are as follows − Core OS Then is the application layer which has four components, namely Classic, Carbon, Cocoa and Java. Next layer is the graphics system which contains Quartz, OpenGL and QuickTime. The base layer is Darwin which is the Unix core of the system. The structure of the Mac OS X includes multiple layers.

The tenth version of the Mac OS is the Mac OS X which was launched in 2001.

The Mac OS is a graphical operating system developed by Apple Inc.
