This ability to defeat the UHD encryption scheme is called LibreDrive. Yes, I believe I checked the un-HBed SD MKV files as directly ripped from the DVDs. Once it is done, you don't need to mess with it again. Getting the right firmware on your drive is a one-time step. Also, just in the last few weeks, there are some Pioneer drives that have been made to work with MakeMKV that can rip UHDs and do not require flashing a specific firmware they work with the stock firmware. There are sellers that will either sell you an automated flasher that'll help you flash your drive or sell you a new, tested drive that has been flashed appropriately. Once your drive has the right firmware, then MakeMKV can defeat the encryption scheme on the UHD and rip it just like a regular blu-ray. The thread you found, Ultimate UHD Drives Flashing Guide, lists all the known optical drives that work, lists the firmware levels that work, has links to where you can download the firmware, and lists instructions on how to flash the firmware (on your Mac, it is a command line thing). If in the market look to the MakeMKV forums for.

4k UHDs, however, are tricky because they have a more complicated encryption scheme. Good for reading 4K UHD BluRays but it has its limitations.will allow you to flash the drive through them. MakeMKV can make just about any modern blu-ray reader work for regular blu-rays. Like AngryVirginian said, you need the right firmware.
