Find Mac OSX version installed using AppleScript

Question

How can I find which version of OSX is installed on my Mac by using AppleScript? I want to install an app programatically and run different pkg files based on the version.

Answer 1

I'm not on a Mac, so there may be a better way to do this, but the first approach that comes to mind is just executing a shell command to query the OS version.

Based on these references, you probably want to do something like:

set os_version to do shell script "sw_vers -productVersion"
