MacOS (operating system)

Mac or MacOS is the name of the operating system developed by Apple

for the line of computers created by the same company. MacOS itself
not just an operating system, but a family of systems that have evolved
evolving through different versions over time. The
The main characteristic of the Mac operating system is that it is designed
to function optimally on Apple devices.
Its name means 'Macintosh Operating System', referring to
the Macintosh, a desktop computer created by Apple. MacOS is
a graphical environment OS, so like other references of
world of computing such as Microsoft Windows and Linux, offers a
virtual environment in the form of a 'desktop' that facilitates interaction between the
computer and the user.
MacOS has followed a design line that splits into two lines. In
In the first place, there were the Mac OS operating systems.
classics, which were released during the 90s and early
from 2000 for the Macs of the time. However, Apple
changed UNIX as the basis for the architecture of its OS, being this the
origin of the line of operating systems MacOS that we know today.

Features
The Mac operating system family has the features that
described below:
The Mac operating system follows Apple's compatibility line,
therefore allows communication between MacOS and other devices
created by Apple such as the iPad, appleTV, iPhone, etc.
Due to its architecture, MacOS has a file system
own, so it cannot natively process the files or
programs with formats usually used for Windows or
Linux.
It is the second most used operating system in the world, which
which demonstrates its success and acceptance among consumers.
Starting from the Mac OS X version, it began to use an architecture
based on UNIX.
The premise of Mac is to provide a friendly virtual environment for
users and a simple way to run software. In fact, it was the
 first operating system to be compatible with the use of the mouse
as an input device.
MacOS is installed by default on manufactured computers
by Apple. In addition, in these cases, the computer usually includes
software like Finder, Safari or Launchpad.
Like Microsoft Windows, it is a commercial software.
closed code.
MacOS employs an encryption system that prioritizes privacy and
user safety.
Its architecture allows for the installation of another operating system on it.
computer without the need to uninstall MacOS.
Uses processors from the Intel family to operate.
It has a wide support of compatible software with the
platform.

Versions
The operating system versions for Apple computers are separated
into two groups, where the first corresponds to all those created
between 1984 with the arrival of the first operating system from Apple. The
second group, responds to the era of UNIX architecture in which it was based
Apple to develop the different versions of the X series. We will describe
the most important versions of each line.
System 1
It's the first operating system created by Apple in 1984 and marked a
a new paragraph in the world of computing, as it was the first to
offer a graphical interface aimed at user interaction with the
computer. In addition, it was compatible with the use of a mouse.
had the use of menus, icons, and other desktop elements that
they made it easy to use the computer.
System 2
It arrived in 1985 as an improved version of System 1. This included the
AppleTalk, a series of protocols that allowed for the operation of the
computers within a local network and increased the list of devices and
peripherals that could be used with the computer. Similarly, it allowed
create subfolders (folders within other folders), something that was
impossible in System 1.
System 3
It was released in 1986 alongside the Mac Plus computer. On this occasion, the
the new operating system provided greater stability and better use of the
system resources. Likewise, it had the Disk Cache, a
feature that allowed to temporarily store those routines
execution of software and commands that a user was carrying out in the
computer. Regarding the visual environment, System 3 provided many
customization options for the graphical environment, making it possible
modify the size of icons and windows.
System 4
Although it did not provide many improvements nor represent a significant leap with
regarding System 3, this new operating system released in 1987 added
new tools like AppleShare; a search engine that allowed
obtain the address of the files stored in the system. Likewise,
it had broader support for input devices such as
printers and monitors.
System 5
It was an update of System 4 released in October of the same year.
System 6
It arrived in 1988 and represented an important leap in terms of the
possibilities it offered compared to its predecessor. Thus, it was the first
version of the Mac operating system that made development possible
different tasks through the windows executed on the screen.
Likewise, it displayed colors on the screen and featured a bar of
tools similar to the taskbars of modern operating systems.
System 7
System 7 was released in 1991 as the first MacOS compatible with the
32-bit memory addresses. Likewise, it still had
added features in System 7 and made small improvements to the
the same, like the option to perform multiple tasks more comfortably
and take advantage of the power of more RAM in the computer. Everything
this, without mentioning the new graphical interface that made greater use of the
colors than their predecessors.
Mac OS 8
He saw the light in 1997 and took full advantage of the power of the new ones.
computers of the time. This software allowed a user to be able
to update software or the operating system itself without having access to
internet. Additionally, it was the last Mac OS to use a based architecture.
in Motorola processors.
Mac OS 9
It arrived in 1999 as a version that added small improvements to it.
offered by its predecessor, Mac OS 8. This operating system represented the
end of the era of classic Mac OS.
Mac OS X 10.0 Cheetah
It was the first operating system of the Mac OS X series, thus beginning
the modern MacOS based on UNIX architecture. Cheetah was released in
the market in 2001 had multiple innovations compared to what had been seen
previously: I had greater support for security and privacy of
user, a much more attractive graphical interface and allowed installation and
download drivers from the same system.
Mac OS X 10.1 Puma
It appeared six months after its previous version. This added improvements to
internal level that improved system performance.
Mac OS X 10.2 Jaguar
It was released in 2002 and again, it focused on optimizing performance.
from the team. Likewise, it provided support for networks and offered multiple
updates to improve graphics card usage and ensure a
better security for the user.
Mac OS X 10.3 Panther
Released in 2003, it offered a fresh and modern graphical interface.
It made it possible to search for files within the system in a way
much faster and allowed fax support, something that proved very useful
for office environments.
Mac OS X 10.4 Tiger
It was the first Mac OS to integrate the iconic desktop Widgets.
(calculator, calendar, clock, etc).
Mac OS X 10.5 Leopard
Apple began distributing this operating system in 2007, offering
new features like the Time Machine backup system and others
interesting software such as iChat, Dashboard, and Dock.
Mac OS X 10.5 Snow Leopard
It arrived on the market in 2009 as an improved version of its predecessor. Its
processing speed and flow were much more stable than in the
previous Mac operating systems.
Mac OS X 10.6 Lion
It was the first operating system to integrate the Mac App Store, as well
allowed to run applications in full screen.
Mac OS X 10.7 Mountain Lion
It was introduced in 2012 as an operating system that could be accessed by
through the Mac App Store. It integrated many applications and functionalities
from iOS to its interface, so it also began to showcase the new
compatibility approach that Apple was seeking in its devices.
Modern versions
The later versions stopped using names of
big cats and give way to the most recent operating systems
of the company. They are:
Mac OS X 10.9 Mavericks
Mac OS X 10.10 Yosemite
Mac OS X 10.11 El Capitan
Mac OS X 10.12 Sierra
Mac OS X 10.13 High Sierra
Mac OS X 10.14 Mojave
Mac OS X 10.15 Catalina
