A Comprehensive look To the History of Mac OS X

MacOS is the Apple Mac OS and Apple Macintosh operating system, the state-of-the-art version of which was first introduced in 2001, called Mac OS X.

17 years ago, on April 4, 2001, Apple introduces the first version of the Mac OS X operating system

(the letter X is actually a Roman numeral and equivalent to 10), which was a fundamental change.

The operating system was renowned for its simplicity, apparel beauty, advanced technologies, various applications, security and fast access options.

Features such as Spotlight, iCloud, and so on – have made OS X more attractive to users and experts.

Thanks to the excellent integration of the operating system with Apple’s hardware, users could easily do their work.

OS X quickly and unwantedly became a brand for Apple and the Mac,

and now more than 14 newer versions are being release.

Mac OS became more complete after the release of iOS because

it was inspired by iOS and now the two operating systems are at least as seemingly similar to each other.

In this article,

we want to look at all the versions of the operating system

that were release after 1380 – including the Mojave Edition to be release this year – to see how the Mac OS evolve over time.

Chita or OS X 10

The first version of OS X is known as Cheetah and is the 10th edition.

Chita is a very big update to the classic Mac OS 9 operating system

and is somehow a successor to the classic version.

Chita was introduced at the end of 2000 and during the Macworld Expo event in San Francisco. With the introduction of Chita, Apple also unveiled the Aqua interface, and the news was no longer classic.

In the Aqua interface, the buttons for resizing windows are colored and the icons also look more realistic.


Apple, along with the introduction of various features of Chita, also unveiled the Dock bar, which is one of the key elements in the beauty of the operating system, and continues to be a part of its beauty due to Dock.

A number of modern applications such as Mail, Address Book and TextEdit were introduced during the launch of Chita.

Puma or OS X 10.1

Version 10.1 is known as the OS X called Puma, which was introduced in 2001 during the Macworld Expo event in New York.

Puma was a relatively important update that made it possible to move more quickly between menus and the process of logging in was faster than before.

Some optional settings and configurations, such as the possibility of docking, have also added new menus for controlling volume and battery life.

The iTunes, combined with the Puma version, was integrated with the operating system, which also has the ability to burn CDs and could play DVDs and support cameras and music players.


The DVD player feature in this version of the operating system was call iDVD, which at that time had a lot of performance for users.

For example, in the Mail app, a feature was add that split spam emails from other emails and put them in a folder call junk.

The iChat app was launch with the Jaguar version as its default, and serves as the default messaging app for users.

 This app was integrating with some features of the AOL Messenger.


In updating Jaguar, the Fender (similar to this PC on Windows computers) was equipped with seamless search capability; OS X 10.2 also made it possible to magnify the display, allowing users to execute various applications using voice commands.
