I had an 2008 8-Core with an LG GGW-H20L and it worked PERFECTLY. I recently sold it for a 2010 6-Core Mac Pro and installed an LG WH10LS30 from NewEgg into the bottom optical SATA drive. My system doesn't crash as some reported, it recognizes the Blu-Ray drive, recognizes a Blu-Ray disc and asks what to do. Yet when I attempt to copy files via Finder onto a BD-R, it states there isn't enough room. Upon researching I discovered the drives can not be used in OS X. I've researched and researched but have not learned of a possible fix. Does anyone know if flashing the firmware (which is 1.0 on the WH10L30) work (such as flashing the firmware to the GGW-H20L)? I realize I should have researched before spending $99 at Newegg, but I've never read of this happening in OS X. Desperate here, I'll do anything for help! Thanks!!!
