What do I have to download to watch bluray discs on my mac

Mac-Go works great as blue ray player.

It's the only solution that I'm aware of at the moment.

Happened to just see this: Aurora Blu-ray Player for Mac. I haven't heard any reviews about it though so can't say if it's better or worse than Mac Blu-ray Player.

My using is also MacGo Mac Blu-ray Player. You could find many resource on the internet such as http://download.cnet.com/Macgo-Mac-Blu-ray-Player/3000-13632_4-75453324.html

This is also what I'm using currently. I believe this is the original and best.
