Macs won't recognize Blu-ray devices because Apple chose not to support them in OS X. However, one developer has come up with a way of forcing OS X to accept external Blu-ray players in the form of Mac Blu-ray Player.
Mac Blu-ray player lets OS X recognize Blu-ray devices instantly so you can watch Blu-ray discs. Not only that, but it supports almost every format out there so you can use it as your default player. 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 you need an internet connection, because Mac Blu-ray Player has to acquire a license to play the movie on your system.
When you start it up for the first time, it will 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:
Mac Blu-ray player is fairly basic - there are very few options other than to add subtitles and change the audio track.
It also supports social media - you can post reviews or comment on the film your are watching to Facebook or Twitter which is pretty neat:
Mac Blu-ray Player still feels rough around the edges and you might experience some crashes and instability, but this is the first release and the developers warn that some bugs and problems are to be expected. Macworld recently took a look at it and found that it could be very unstable at times, and also quite random in the way it opens and Blu-ray menus and files.
If you've been frustrated by the lack of Blu-ray player support on Macs, then Mac Blu-ray Player could be the answer.
