How to find out which Mac OS version you have on your Macbook or iMac

To find out which version of Apple’s desktop operating system you have on your Mac, you will need to click on the apple icon in the upper left corner. After that you are going to see a drop-down menu, and in this menu you need to select “About this Mac.”

There will open a new information window where the OS version and its name will be indicated in the “Overview” tab.

It is worth noting that Apple every year releases a major update for MacOS, and small additional updates are released during the year (those, first of all, are aimed at correcting errors). If somebody is asking you which Mac OS version is installed on your computer, most often it is about the major version, that is, the one that is updated every year.

Major update of the operating system receives a new number after the version “10.”, as well as its own name. In the screenshot above, you can see that the major version of the operating system on our computer is Mac OS Mojave number 10.14.

It should be noted that the full version of the operating system cannot be identified in the manner described above. The fact is that each update has not only a digital designation, but also an alphanumeric combination. This information is extremely rarely needed, but it will not be superfluous to know how to find it. This information can be found if you click on an apple in the upper left corner, and when the menu opens, hold down the Option (Alt) button and go to the “System Information” section.

Here, in the left menu, switch to the “Software” item, and then at the right side in the “System Version” column you will see the full current version of Mac OS installed on a specific device.

As you can see, the first method gave us version number 10.14.2, and in the second one –  10.14.2 (18C54).

How to find out which iOS version you have on your iPhone or iPad

It is quite easy to determine which operating system version is installed in your mobile device. To do this, go to the application named “Settings”, and then go to the “General” section.

Here go to “About”.

Among the information about the device there should be the “Version” line – this is the version of iOS currently installed on your device.
