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.
