Even though Mac OSX currently lacks software to play Blu-ray movies, you can run BootCamp off your Mac and use PowerDVD in Windows to play your Blu-ray movie. It's that easy. Lightweight and compact, this external drive can go with you anywhere and will make life easier and a lot more fun. *Note: Apple's QuickTime software does not (yet) support the decoding and playback of encrypted Blu-ray movies. Therefore you cannot watch commercial (Hollywood) Blu-ray movies using Mac OS X. However, if you have Windows XP or Vista installed on your Macintosh, you can use PowerDVD software to decrypt and watch commercial Blu-ray movies via Apple's BootCamp environment.
