Seems like most questions about Macs and Blu-ray drives have to do with video (ripping, playing, copying, authoring). But what about BD-R data discs? I just want to buy an external BD burner and use it to burn BD-R data discs for storage purposes. I've found conflicting reports. Some say that no special software is needed for this, and others say that something like Toast is required. I know I'd need Toast to author Blu-ray video discs. But would I also need Toast to burn Blu-ray data discs, or is Disk Utility (or burn.app) sufficient?
