Understanding Mac OS

What is Mac OS

Mac OS was previously known as Mac OS X and later on people referred to it as OS X simply. This is a proprietary graphical operating system that is designed and marketed by Apple.

Considering the operating system market of desktop and laptop computers, this operating system ranks second to Microsoft Windows. It is also one of the most popular operating systems for web usage.

The first desktop version of the Mac OS series was released in 2001 and was named Mac OS X 10.0. Check out Pros and Cons of Mac OS.

It was used as the primary operating system for the Macintosh line of computers designed and marketed by Apple. It was then updated in the same year and was named Mac OS 10.1.

The nomenclature of Mac OS series is very interesting. Mostly, these operating systems are named after the big cats.

For example, the last release with the name of big cats was OS X 10.8 Mountain Lion. After that, Apple named its operating systems after different regions, mainly of different locations in California.

In 2012, Mac OS was shortened and was called simply OS X. Here, X denotes the Roman numeral, Ten. Later, in 2016, it was termed as ‘macOS.’ This is accordance to the taxonomy of other operating systems developed by the company such as:

The latest version of this series released in October 2019 is named macOS Catalina.

The structure of this operating system is based on Unix as well as different other technical systems that were developed within the period of 1985 and 1997.

Till 2005, there were several versions of Mac OS X developed and released by Apple when they turned their focus on Intel CPU. In 2006, they came up with Intel based Mac in 32 bits and 64 bits.

As for the Apple TV, it uses the updated version of Mac OS X 10.4 Tiger. The features of the operating system include some of the most advanced ones such as:

There are also several other features added to this operating system such as Sheets, Drop Shadows, and Dialogue Boxes.

There are different components in this operating system which enhances the performance of it.

In the more recent versions, Apple has introduced several other useful components. The Automator is one such component that is introduced in the 10.4 version.

This automates different functions, justifying its name. Apple has also used its proprietary Apple Color Emoji font to support the emoji characters.

Apart from that, the Mac OS is connected with different social networks such as Twitter and Facebook. Users can connect to these channels using the share buttons to access content including text and pictures.

The recent releases of Mac operating systems also have a lot of features and applications that originally debuted in the iOS, its mobile operating system.

One of these notable inclusions is Siri, the intelligent personal assistant. This was first introduced in the 10.12 version of the Mac operating system.

The latest versions of Mac OS also have a lot of similarity in its design with the first iMacs such as:

These new features made the user interface even better. If you compare the latest versions with Mac OS 9 and Mac OS X Server 1.0 Platinum, you will see the difference in user experience.

Apple has always tried to change the look and design of Mac OS. There are several tweaks made to the look of the menu bar and the windows.

This operating system and the APIs support all Mac models, especially those that come with high-resolution retina displays.

The Mac operating system is designed according to the guidelines published for the human interface. This provides the users with keyboard shortcuts and a more consistent interface. The features and new applications of the operating system include:

The OpenGL graphics system included on version 10.2 helps in hardware augmented drawing and is called Quartz Extreme.

It is the inner imaging model of this technology that helps in correlating with the PDF or Portable Document Format imaging model. This helps in creating several PDF outputs to use in multiple devices.

You will also get adequate system support from the Mac operating system when you deal with professional image and video formats.

Apart from that, the installed font library in this operating system features several designs of some of the most prominent brands that you may include in your task.

You will also get multilingual support when you use this operating system with its 39 pre-installed system languages.

This means that, irrespective of the system language, you will be able to choose different input methods from the dozens of scripts, including Chinese, while typing a text using this particular operating system.

Finally, the operating system comes with a useful feature that will help you to update the system.

There was a separate software for performing this task in the previous versions Mac OS but in the Mountain Lion version and then after, it was merged with an app.

This app is available exclusively in the Mac App Store. However, the basic mechanism for updating the operating system was unaltered but the download mechanism was fundamentally different as compared to those purchased apps, typically used in Windows operating systems.

For some unknown reason however, this updating function was once again moved to the Software Update Preference pane in Mac OS 10.14 Mojave by Apple.

Background and Architecture

This operating system was introduced by Apple in 1984. At that time, it was considered as the first commercial computer operating system that used the Graphical User Interface, or GUI.

This useful feature helped a great deal in making the operating system much easier to operate.

Also, the navigation became much more accessible to all. This was a significant help especially to the non-technical people.

Over time, the manufacturers developed and upgraded the operating system and now there are many different versions of Mac OS found in the market.

Apart from the common and useful features like the calendars, spreadsheets, and word processor, the manufacturer has also included a few additional features in it.

This has made the operating system even more useful and functional, especially for use in the offices.

The architecture of the Mac operating system includes POSIX at its core.

The system is also built on the XNU kernel and all fundamental attributes and features of the UNIX interface commands are included in its design.

The entire architecture of the Mac OS is, once again, based on the concept of GUI or Graphical User Interface.

Darwin is the open source of this operating system which was further liberated by Apple.

This is made from several different components out of which the two most important ones are Finder and Aqua Interface.

With the launch of the original Mac OS and its updated versions in the subsequent years, the users got a multitasking platform that helped them to perform different tasks concurrently.

The best part of this operating system is that it will not interfere or disturb the other tasks when a user performs a particular one.

The present coding system of Mac OS depends on the layered architecture which has made this system even better than before.

For the coding system, Apple uses the most advanced XCode Interface.

This is a sophisticated interface that supports different programming languages such as:

Another significant move made by Apple regarding the architecture of the Mac operating system is improvising Intel.

This has helped the users in ways more than one such as:

Most importantly, it helped the programmers to have a greater hold over the first party programs and third-party applications.

The programmers can now apply the Automator much more easily and for that they need not have any previous knowledge of programming.

Everything is pre-written in the operating system as one of its specific tasks.

Different Mac OS Versions

Over the years, Apple has come up with several different versions of Mac OS since its launch in the 1980s. Each of these new versions came with different internal code names.

The different versions released in the last two decades at different times are arranged chronologically in the following list and include:

If you look at the list carefully you will notice that all versions of Mac OS, apart from the first OS X beta, are named after big cats and names of regions.

However, internally, all these versions were named after wines, apart from OS X 10.6 and macOS 10.13. Both these versions of Mac OS did not have any codenames.

Later on, Apple decided to change the names of the different versions from wines to different types of apples since 2015. Originality, folks!

Also note that the terms macOS and OX X, normally pronounced as O S Ten, can be used interchangeably. This is because the key functions of the operating systems are similar.
