Burn a Blu-Ray Disk

Thanks for your reply.

Mac OS has long supported burning data to Blu-Ray. It is only that the recent Mac OS version is hit or miss. My LG Blu-Ray drive does work to burn discs from the Finder in old versions of Mac OS X.

I understand the many issues facing Blu-Ray as a video storage medium with all the licensing, cost, copy protection, and other factors. However, I already have a very large collection of videos, much of it on optical discs of one sort or another, and I have had almost no issues with reliability or long term storage (thus far). In fact my son has been telling me for years to move to hard disk based video storage, and I have done that for the most part, but I still like the ability of taking a disc to a family member's house and playing it on their set-top optical player. In my experience very few people out of the general public are geeky enough to have a computer connected TV that would play a USB stick of family videos. And I don't want to bring along a laptop of my own to do it. I want to leave the family history video with them, as a gift, that they can play when they want to. They want something that works like the other videos they play. So I like being able to bring or send something that works for them. I have been doing it for many years and it works well using my older Mac. It was only when I got my Mac Studio that I started having issues with burning Blu-ray Discs.

I know technology moves on, but I also have a laser engraver that requires Mac OS 9 to function. Should I throw away a $20,000.00 laser because it does not work with the latest technology? Instead I have a nice dual processor G4 Quicksilver Mac (and a backup) that boots into OS 9, and I use it routinely. I am not a business. I am a hobbyist. I like the old stuff. And where it is possible, I like the new stuff. Is that so bad?

My wife just read my post and told me that I should mention that I am an old codger who likes doing things the way I do them. I think that is a bit strong, but it is starting to hit pretty close to home...

Thanks again for your comments. I really do appreciate them!

Thanks very much for reaching out with an idea on what might be wrong.

I tried doing that (removing some files). In fact I went all the way down to 10GB with no improvement. And I was able to burn the full 24.5GB folder of files to a BD disc using the borrowed drive. So the amount that is wasted is not the issue in this case. It is simply that the new Mac OS does not support my drive (any more). But thanks for the idea.

In case anyone is wondering, System Profiler does show a 25GB Blu-Ray disc inserted into the drive, so the OS does see and read the optical disc size correctly. But for some reason, they just don't support burning it.

I borrowed another Blu-Ray burner to test with. It is a cheap and slow "Everpower" USB bus powered device, but it works with burning a BD disk from the Finder. Apparently my expensive and faster (and M-Disc & Lightscribe capable) LG burner is not supported by Apple as well as the other drive?

Now what?
