UHD Drive Tool for MAC

[Quirlo]

Hello, i purchased the Buffalo BRUHD-PU3 drive and the firmware needs to be downgraded.
The DVDFAB UHD Ripper does not work with the firmware installed.
I have just spent over € 500,00 for this UHD "#@*+" and the proposed UHD Drive from DVDFAB now doesn't work on the MAC Plattform.
I appreciate any friendly suggestions that you might have. This is just pure misery right now. Thanks for your answers.

I am at it again, trying to make my buffalo BRUHD-PU3 work. My DVDfab is running on a MAC with Big Sur.
Actually I am not sure if the drive works like it should.
Since DVDfab Drive tool does not run on Mac, I have found another drive tool running on a Mac.
The first part of the tool is without cost, but when you downgrade you must pay.
This tool suggests the folowing:

19:08:38 Gewählter Laufwerk 1 - [BUFFALO-Optical Drive], Firmware:BU10

19:08:38 Zugriff auf Firmware-Information erfolgreich! Firmware: BU10-00, BU10-01

19:08:38 Gewählte Firmware: BU10-00

19:08:38 Auf Klick auf Button "Firmware Downgrade" warten zum Downgrade.

It seems there are two firmwares BU10-00 and BU10-01
The Tool has selected BU10-00 and wants to downgrade.

Please comrades, help me on this one. Which Firmware do I need ?

Appreciate any help ! Thanks in advance.
Best wishes,
Quirlo
