# How to check your macOS version number

## What is an operating system version number?

A version number is a unique set of numbers representing the specific release of an operating system.

The macOS version number follows the format of major.minor.patch. For example, here’s what each component in **12.6.1**. means:

- **12** is the major version;
- **6** is the minor version;
- **1** is the patch version.

If you want your team to use macOS 12.6 or a later version, enter, for example, 12.6.0 in the Device Security Posture Monitor Operating system version field.

## How to check your macOS version number

To find the macOS version number on your device, you can run the command line **sw_vers** in the Terminal app or go to **Apple** > **About This Mac**.
