you can also cheat and get the product version directly (though this is not considered the correct method by apple):

? (defun mac-os-x-version ()
   (ccl::with-autorelease-pool
       (let* ((plist
               (#/dictionaryWithContentsOfFile: ns:ns-dictionary #@"/System/Library/CoreServices/SystemVersion.plist")))
         (ccl::lisp-string-from-nsstring (#/valueForKey: plist #@"ProductVersion")))))

? (mac-os-x-version)
"10.6.4"

warmest regards,
