Reinstalling macOS won't remove your personal data. I feel the frustration.When you see a window with the option to reinstall macOS, this means your Mac has started up from Recovery. Just takes a few minutes to read and research to know before posting basic questions. Yes, there can absolutely still be other issues, but simply thinking you have a bad disc, or that MakeMKV isn't doing its job, may lead you nowhere. People are surprised when they follow these basic first steps and then it works. People don't realize that they need to submit their dumps. Even discs that look perfectly clean still have to be cleaned. This comes up with every new release, and there's still a lot of people learning, which is why I mention it. Was replying partly to Randude14 who simply said they were having 'trouble reading' without being clear on the exact issue / error message, and partly to the thread at large. And I had the latest keys and if you saw my post I submitted the dump in the event there was an issue or different key needed. I still always attempt cleaning as the first step as well as restarting the software, the drive, and reinserting it.

my discs are brand new and show no visible issues.
