To help you get the most out of your mac!
When sharing to Blu-ray from Final Cut Pro X, Motion 5, or Compressor 4, the Blu-ray (BDMV) folder on the resulting Blu-ray disc appears as a QuickTime file and it will not open. This occurs in OS X v10.8 Mountain Lion. Any Blu-ray disc (purchased, burned, or disc image) will appear this way.

The outside of the box said "Windows base machine or better", so I bought a Mac.
