MakeMKV no longer ripping on my Mac with the new Catalina update...getting errors

[Samebeef]

Hello everyone,,
as the title states I am getting errors trying to rip my movies. everything was working perfectly until I updated my iMac with the Catalina update. all of a sudden I am getting errors such as:

Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - AUTHENTICATION FAILURE' occurred while issuing SCSI command A30..00200740100720..0C584BC2BEE573312E4BFE0320244B9D474 to device 'IoKit:IOBDServices:8bdbd0eee8f1a2c0:HL-DT-ST BD-RE BP50NB40 1.02'

and

Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED' occurred while issuing SCSI command AD010..080002400 to device 'IoKit:IOBDServices:8bdbd0eee8f1a2c0:HL-DT-ST BD-RE BP50NB40 1.02'

DVD's are ripping just fine (for now) its just the blu rays...the drive shouldn't be failing as it can play Blu-ray's and the fact that I just got it like 2-3 week's ago.

Not sure if this will fix the problem, try a PRAM Reset

Seems like the Catalina update is causing all sorts of headaches across numerous apps. I have seen report of 4k and 5k monitors now suddenly not working at full resolutions, and some other hardware not functioning as previously.

Do you have a clone you could roll back to of the base Catalina (which I assume from your post was working fine?)
