Some people are very tech-savvy and want to own everything latest on the market. Just like people update or change their phones, they also want to have the latest version of everything they own, be it a smartwatch, laptop, earphones, or even operating systems.

An average Mac user does not care about the operating system he/she is running if it is working just fine. But sometimes, there may arise a problem, and to resolve it, knowing the macOS version becomes mandatory. To allow you to do so is the purpose behind this blog.

There are several reasons why you may need to know the macOS version, such as:

  • Problems in installing an application,
  • Non-compatibility with a new feature, or
  • Troubleshooting purposes.

For some, it is important to know the version so that they can upgrade it to the latest one. Whatever is your reason for ascertaining the macOS version running on your Mac, this is where we’ll tell you how to do it.

How to Check the macOS Version Installed On Your Mac?

Follow the steps below to check the macOS version installed on your Mac:

  • Step 1 – In the top-left corner of the screen, go to the Apple menu by clicking the Apple icon.
  • Step 2 – Click on “About This Mac.”
  • Step 3 – An Overview window will appear on your screen, showing the macOS release and version running on your device.

You can also see the build number by clicking on the version number, but it is not useful for the average users. If you have an older version of macOS, it may be called “OS X” instead of just “OS.” You may know about the Mac model and when it was built, the Mac serial number, the system software version, etc.
