If you use both Mac and Windows and need a player that can play Blu-ray on both platforms then take a look at Blu-ray Player for Windows.
Blu-ray Player for Windows recognizes Blu-ray devices and internal Blu-ray players instantly, meaning you can connect a Blu-ray player to your PC and watch Blu-ray discs. Not only that, but Blu-ray Player for Windows supports almost every format out there so you can use it as your default player if you choose. Even better, for the first three months it's completely free to use, although a watermark is placed on the screen and some features will be deactivated.
To play protected Blu-ray movies however, you need an internet connection because Blu-ray Player for Windows has to acquire a license to play the movie on your system. Blu-ray Player for Windows is fairly basic. There are very few options other than to add subtitles and change the audio track. When you start it up for the first time, it will also prompt you to select which files you want to associate with it so it won't take over your media files unless you allow it to.
Blu-ray Player for Windows also features a certain amount of social media support. You can post reviews or comment on the film you're are watching to Facebook or Twitter, which is a pretty neat feature.
Blu-ray Player for Windows feels a bit basic in design and you might experience some crashes and instability, but bear in mind this is the first release and the developers warn that some bugs and problems are to be expected.
If you're looking for a cross platform Blu-ray player, then Blu-ray Player for Windows could be your answer.
