If you're not sure what version of OSX your Mac is running, there's an easy way to find out.

Click the Apple logo at the left of your menubar and select About This Mac.

 
That will bring up this window showing the OSX Version number, among other things:

See the green box below for the major version name.


Click the Version number, and you'll see the Build number.


Click it again, and it will show the Serial Number.


If you need the serial number, write it down, as you can't copy it.
