How to Check Your macOS Version
Using the Apple Menu
To find your macOS version, click on the Apple logo located in the top-left corner of your screen. This opens the Apple menu.
In the Apple menu, select the option “About This Mac.” This action opens a new window that provides information about your Mac.
The “About This Mac” window displays the name of your macOS (e.g., macOS Big Sur) and its version number (e.g., 11.0.1). Make a note of this information.
If you need the build number for troubleshooting or other purposes, click on the version number displayed in the “About This Mac” window. The build number will appear right below the version number.
Using Terminal (alternative method)
If you prefer using command-line tools, you can use Terminal to find your macOS version. Open Terminal by navigating to Applications > Utilities > Terminal.
In Terminal, type the following command and press Enter: sw_vers
The terminal will display information about your macOS, including the ProductName (macOS name), ProductVersion (version number), and BuildVersion (build number).
Understanding macOS Version Numbers and Names
macOS version numbers follow a structure of “major.minor.patch” (e.g., 11.0.1). The major number represents a significant release with new features and changes, while the minor and patch numbers indicate smaller updates and bug fixes.
If your “About This Mac” window only displays the version number, you can match it to the corresponding macOS name using the table below.
Each macOS version introduces new features, improvements, and changes. Familiarizing yourself with these updates can help you make the most of your Mac and understand the benefits of upgrading to the latest macOS version.
