Is it possible to play a Blu-ray Disc on iMac? There is no any drive with my iMac and I know apple doesn't have program that could play Blu-ray until now, so can anyone give me some ideas about how can I make my iMac play Blu-ray disc movies?
You might to check out this MacWorld url.

There are several Blu-ray external USB drives available, but the url above will point you in the right direction.
