Question: macOS Blu-Ray support for data disks?


I use BD-R and BD-RE disk for data storage.

Does macOS Sierra or High Sierra support burning R disks (burn once) or -RE disk (rewritable burn-many) or -RE (dynamic writing like a hard drive)?

NOTE: I am not authoring, burning or watching Blu-Ray video disks - anything in regard to Blu-Ray video is irrelevant to this post. This question is about macOS native ability to use Blu-Ray disk for data storage; writable, rewritable and dynamic writing.

null-OTHER, macOS High Sierra (10.13.3), null

Mac OS has never natively supported Blue Ray. Also using any DVD for a backup is a VERY VERY flawed strategy. It is flawed due to insufficient capacity and shelf life of the media. A much more reasonable backup strategy is using external HD(s) and creating either a bootable clone (SuperDuper! or Carbon Copy Cloner apps) or using Time Machine per How to use Time Machine to back up or restore your Mac - Apple Support. A wise backup strategy would be using a minimum of 2 backup EHD's, price should not be an objection as EHDs are very reasonable. My (and many other experience users on these forums) preference is OWC Mercury Elite Pro: Production-Grade External Hard Drive

The Finder Burn feature will work with BD-R and BD-RE discs (in UDF 2.01) in one closed-disc session. Dynamic writing requires formatting by third party software capable of doing such.

I appreciate your post but Blu-Ray is a reliable archive format, a format that includes M-Disc (Bly-Ray). Blu-Ray and M-Disc (Blu-Ray) are used by governments and military agencies for archiving.

I already use Time Machine, along with a redundant RAID drive and hot swappable offline copies. But in the end, hard drives have a much shorter life span than optical disks, especially when used for long term archiving.
