I'll run the latest OS update and see if it changes anything.
I had to re-download MakeMKV, so it is the latest version of that.
The drive is plugged into a USB hub, which is then plugged into the Mac. It's a Mac mini, and the drive requires two USB ports, so plugging it directly into the Mac isn't really an option.
If necessary, I can connect the drive to a windows machine, but this Mac is what I use 90% of the time.
If using a USB hub, make sure it is a powered one, not one that gets power from a USB port.
It would be quicker and easier to connect it to a Windows PC for flashing purposes as it only takes a minute.
Cheers

I updated to the latest version of Sonoma. Still have the same issue where it doesn't show a usable identifier for the drive. I'm going to guess that Sonoma changed something about how that identifier is obtained and MakeMKV hasn't updated to handle that change yet.
Ended up flashing it with the visual flasher on Windows.
