If you prefer to use Terminal, search the internet using something similar to If you use the OnyX app (from titanium software) it can be done from the Maintenance tab. change your DNS server(s) to something different from what you have nowįlushing the DNS cache is done a little differently in each major release of macOS.If your problem is ultimately because of inability to download hk keys from hkdatastore.tk then it should be pretty easy to try his solution: The two of you are not describing identical diagnostics, but fundamentally the problem is similar - unexpectedly you can no longer read blu-ray discs. This may be a long shot, but in a post today by user iliveinabox05 he also found reference to SDF in his debug file. I'm running on Arch Linux.I notice in your debug log there are lines referencing “No SDF”. The drives are the same model, the LG BH16NS55, and both have had their firmware flashed to WH16NS60 1.02MK. The drive refuses to take any and all Blu-ray discs, including ones that I know for a fact work. I've tried restarting and updating my computer, to no avail. I've never heard of a drive failing because it couldn't read a disc properly. I refuse to believe that this is a hardware issue, since it seems impossibly unlikely that two drives (albeit with the same model number and firmware) would have the exact same problem after failing to read the exact same disc. I did the same as I already said, and the exact same thing happened. After patching the firmware so it works well with MakeMKV (LibreDrive and all), I ripped a Blu-ray as a test it worked fine, so I got to work on this disc. The first time, I put it down to a hardware failure, assuming the blue laser had died, and bought another. The really weird part is that this is the second time it's happened in about a week. CDs and DVDs continue to work fine, however.

It doesn't show anything in lsblk, no disc appears to be able to mount, nothing. The drive makes a whole bunch of seeking noises, and spins up a bunch of times, but never gets anywhere, and eventually stops trying. The problem is, after using MakeMKV to try and backup the disc, the drive is unable to read the disc at all, and after this point, the drive cannot read any Blu-rays at all. I've been attempting (somewhat fruitlessly) to rip a Blu-ray disc that appears to have a bad sector on it (thanks, BBC).
