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

You can get version from the Finder app as well

tell application "Finder"
    set os_version to version
end tell

display dialog os_version

On my machine this displays "10.5.8".
