How to Find Your Mac Version

Each new release of the Mac operating system includes its own unique version number. Knowing your operating system’s version number will help you to know whether or not your computer’s software is up to date. Additionally, as a Mac beginner user you may need to provide a version number if you ever need to consult Apple’s customer service. You can find out which version of the Mac operating system your computer is running by following just a few basic steps. When using a Mac for beginners, its always important to find out what software version your machine is running as soon as possible.

Step 1

Start by clicking on the “Apple” button at the very top of your computer’s desktop. New Mac users should note that this icon isn’t actually labeled “Apple,” but instead features a tiny image of the Apple company logo. Clicking the “Apple” button will reveal a new drop down menu on screen.

Step 2

Select the option from the “Apple” menu reading “About This Mac.” A new program window, also labeled “About This Mac,” will appear over top of your computer’s desktop.

Step 3

Look just beneath the “Apple” and “OS X” logos at the top of the “About This Mac” program window. The number next to the word “Version” represents the current version of the operating system that is installed on your Mac computer. If a more recent version of your computer’s software is available, click the “Software Update” button on screen.

You can close out of the “About This Mac” window and return to your desktop by clicking the red “X” button in the upper left corner of the screen.
