How to update MacOS software on my Apple computer? Step by step guide

Today the versions of the Mac OS Operating System have been updated. That is why when one goes to the market a new name is placed, and also every time they are advanced they are identified with a number different from the others, indicating that this is a new version and that it is already available.

In case your MAC OS has any version other than those already updated, it is recommended that you upgrade it through the Apple store , since they include updates so that it is more secure and so that the apps are the newest.

It should be noted that “Apple” usually designs its “Hardware,” which includes each of its “drivers.” This makes it compatible with every Mac computer .

What unique features did the first version of Apple MacOS OS have?

The first version of MacOS OS had a “GUI”, which is a graphical user framework that was easy to use, this being a real necessity because the existing computers were handled by commands.

Now, this version had a public mouse , which by 1984 was not very common. Although we must clarify that it was not a novelty for that time, because Lisa already used this device to be able to interrelate with the interfaces.

But the first Macintosh was the one that made users use this device for the first time. Another important feature of this system is that was extremely economical and easy to acquire.

On the other hand, this version had certain types of problems, motivated that when it was released in 1984, its speed and strength was somewhat slow; however, the engineers behind this model were modernizing it to speed up its operation .

In addition, it had a microprocessor with CISC technology, increasing its speed from 5 to 8 MHz, and with a screen of about 384 x 256 pixels. It also had about 128 KB of RAM, which is equivalent to about 128 Kibibytes or 128 x 2 ^ 10 bytes and not kilobytes (or Kb), being that through this it was given its first name: the «Macintosh 128K ».

Its 9-inch screen had as a accessory a mouse and a traditional floppy drive of 400Kb , joining all these in a single mechanism, which provided comfort when moving it to any place. It is for all these characteristics that the first Macintosh has been a milestone for personal computers for history.

Timeline of all versions of the MacOS operating system that exist

Many things have been transforming into the universe of technology since January 24, 1984, when the Apple Computer Inc. company launched its Macintosh 128K . It was a personal computer equipped with a Mac OS operating system.

1984: System 1

It had windows, a desk, a mouse, icons, scrollbars and menus. In addition, it had a bin where those documents or files that the user would not use were staying, so once the computer was restarted they disappeared. But I didn’t have the option to work with several applications , since I didn’t have virtual memory .

A “folder” could not be created on top of another “folder”, since the files were stored in the same address on the hard disk , creating a note for each one. This with the intention that each finder appeared as a file that was inside its folder.


1985: System 2

New improvements were made, through which the speed was much better, eliminating the commands to return and finish the session. Also, other activities were added such as: turn off, be able to create new folders, have a desktop printer , and make the items look vertically and with smaller icons.
