okay...

So I've asked this question before (setting up Libre-Drive on my Buffalo disc drive/reader) but in trying to do a "flash install" as its put, none of the files I've downloaded from the link provided are compatible with my iMac running on the latest OS. Are there Mac friendly files I can get ...

Is the Archgon MD-8102P-U3YC-UHDB-K a good drive for UHD writing/burning for Mac OS?

Thanks for the tip
But, what do you mean by “flashing?”
...sorry, not THAT tech savvy

took a photo of the model details on its base... easier than describing it

LibreDrive Information
Status: Possible, not yet enabled ...

So then is there something I’ve done wrong with my attempt to enable the extension?
Should I try again?

When I open MakeMKV is always displays this message:

MakeMKV v1.12.0 darwin(x64-release) started
Optical drive "BD-RE BUFFALO Optical Drive BN10d" opened in OS access mode.
Optical drive "BD-ROM WD Virtual CD 1110 1032" opened in OS access mode.
It's highly recommended to install DASPI kernel ...

I followed the steps here that you've given
(restarting the Mac, opening terminal in recovery mode and typing in:
csrutil enable --without kext, then reboot

but my MakeMKV still says opened in OS access mode

Is it because of my OS? Should I not bother if I'm running on macOS High Sierra (10.13.3)?
