Steve Jobs famously called Blu-ray's licensing (presumably mandating annoying DRM requirements at the OS, driver, and device level) a "bag of hurt" - but it probably didn't hurt that Apple already had a competing "iTunes" movie download store, whose annoying DRM requirements Apple happily implemented at the OS, driver, and device level.

In any case, rip/mix/burn never really made it to iDVD or iMovie (or QuickTime Player), and Apple never shipped Blu-ray movie player software for Macs.
