If you are a Mac user, you may at some point need to know which operating system (OS) your computer is running. This information can be important for troubleshooting issues, downloading software updates, or verifying system requirements for certain programs. In this article, we will go over a few simple steps to help you determine which OS your Mac is running.

Using the Apple Menu

The easiest way to check which OS version your Mac is running is to use the Apple Menu. Here’s how:

  2. In the left-hand sidebar, click on “Software”.
  3. The version of your Mac’s OS will be displayed in the right-hand pane.

System Information provides more detailed information about your Mac’s hardware and software, so it’s a good tool to have on hand if you need to troubleshoot issues.

One key takeaway from this text is that there are multiple ways to find out which operating system (OS) your Mac is running, including using the Apple Menu, System Information, and Terminal. Understanding your OS version is important for troubleshooting issues and ensuring compatibility with certain apps and software. It’s also important to regularly update your Mac’s OS to ensure security and optimal performance.

Using Terminal

For advanced users, there is a third way to check your Mac’s OS version using Terminal. Here’s how:

Terminal is a powerful tool that allows you to access many of your Mac’s internal settings and configurations. However, it should be used with caution, as making changes to these settings can cause problems with your computer.

Key takeaway: It’s important for Mac users to know which operating system their computer is running, as it can help troubleshoot problems and ensure compatibility with apps and software. The OS version can be checked easily through methods such as using the Apple Menu, System Information app, or Terminal.

Understanding OS Version Numbers

When you check your Mac’s OS version, you’ll see a number that looks something like “10.15.7” or “11.0.1”. But what do these numbers mean?

The first number (the “10” or “11”) represents the major version of the OS. For example, macOS Big Sur is version 11. The second number (the “15” or “0”) represents the minor version of the OS. This number is incremented with each update that Apple releases. The third number (the “7” or “1”) represents the patch version of the OS. This number is incremented for bug fixes and security updates.

A key takeaway from this text is the importance of knowing which operating system (OS) your Mac is running. This knowledge can help you troubleshoot issues with your computer and ensure compatibility with certain apps and software. Additionally, regularly updating your Mac’s OS can help prevent security vulnerabilities and keep your computer running smoothly.
