What and how many versions of Apple’s Mac OS Operating System are there to date? 2020 list

Today versions of the Mac OS Operating System They’ve been updated. That is why when one goes on the market a new name is placed on it, and likewise each time they advance they are identified with a different number from the others, indicating that this is a new version and that it is already available.

In case your MAC OS has a version other than the ones already updated, It is recommended that you enhance it through the Apple store, since they include updates so that it is more secure and so that the apps are the most innovative.

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

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

The first version of OS MacOS had a “GUI”, which is a user graphic frame that it was easy to use, this being a real necessity due to the fact that the existing computers were managed by commands.

However, this version had a public mouse, which for 1984 was not something 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 got users to use this device for the first time. Another important feature of this system is that it was extremely economical and easy to acquire.

On the other hand, this version had certain types of problems, because when it was released in 1984, its speed and strength was somewhat slow; however the engineers who were behind this model they were modernizing it to streamline 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 KiB 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 I had as an accessory a mouse and a traditional floppy drive 400Kb, uniting all these in a single mechanism, which provided comfort when moving it anywhere. It is for all these characteristics that the first Macintosh has been a milestone for personal computers in history.
