OS X Blu-ray support to read / write BD-R discs for data storage What I'm looking to achieve is to write (and read) data files on BD-R discs for storage / backup / archive purposes, just like one can do with CD and DVD discs. For clarity, I am not interested in copyrighted / encrypted / DRM'd BD-ROM HD video material / films, just plain data accessible through Finder.

Obviously, I would have to provide myself with a Mac compatible Blu-ray writer / burner first.

That being said, does OS X support reading and writing data files from / to BD-Rs natively without 3rd party software? If not, is there any open-source software that would allow that?

I'm on a MBP with Yosemite and have never used an optical drive on OS X, so I'm not familiar with that process. Online documentation on Blu-ray for Mac / OS X is pretty sparse and I can't find an authoritative source on the matter. I'd be hard-pressed to believe I'm the only one who is trying to achieve that.

Thanks!
Reading the original post carefully, I can confirm that nothing special is needed to mount a blank Blu Ray Disk in the Finder, and then burn data to it with Mac OS X's built-in disk burning tool. I just did this yesterday with a 25GB BD-R. This worked perfectly with an external LG Bluray burner I just bought from OWC. Hope that helps.
