Mac support for Blu-Ray
For this specific model according to "Allthingstech" (in a comment on web store):

  Purchased this for my new Macbook Pro with Retina Display. The MB can recognize the drive regardless what the Lg packaging says. Had to use third party software ( Mac Blu-Ray Player) for playback. (…) So far the drive has worked perfectly with stellar Bluray playback and absolutely no stuttering or lag.(…)

And OS X since Leopard can read Blu-Ray-Rom with any drive, the problem is to read protected video (all commercial Blu-Ray).
