Thanks, John. But no, I'm using a MacBook Pro running Mavericks.
Do be aware that if you go to DVD or BluRay you MUST keep Encore CS6 since there is no Encore CC
CS6 is the final Encore http://www.adobe.com/products/encore/faq.html
Also be aware that Encore is NOT supported for Mavericks (see note inside above link) and some people are having problems
