This DVD was clearly misrepresented on Amazon. The packaging is almost identical to the product I thought I was purchasing - Mac OS X Leopard Operating System. The description was extremely spartan, and didn't include the words 'Tutorial Video' or the rather important fact that the video was filmed entirely in French !!! The seller doesn't appear to be French, it was posted from Scotland, and it was advertised on the Amazon.co.uk ( not French again ). So why on Earth would the seller not advertise the product as a 'How to use Mac OSX Leopard tutorial', and omit the fact that it is in the French language ? ? ? Extremely strange listing. I don't for a moment believe I am the only person duped into thinking I was purchasing the Operating System. I posted the item back and received a refund, but what a ridiculous waste of time and money!
