Yes. My Apple Silicon Macs run an arm64 release of MakeMKV.

Running an unsigned kernel extension in modern macOS is pretty hard and should be avoided generally. Securely extending the kernel in macOS It might be easier to do on an older Intel mac. Or see how well that drive works on a Windows or Linux machine. Or, depending on how many HD-DVDs you have, buy ...

Thanks for the quick reply. Sure - info and logs attached for both the failing discs.

Have you tried power cycling your drive?

The current beta key is valid until the end of May. MakeMKV is free while in beta If you purchased a license you should've gotten an email with your permanent key. Either way, you'll have to input the key into MakeMKV and restart MakeMKV. Find the 'Register' menu item in the 'Help' menu of MakeMKV t...

It has been a while since I've used macOS Sierra. I'm pretty sure this is just Apple's Gatekeeper getting in the way. Instead of double-clicking on the app, right-click (or Option click) and select Open. If I remember correctly, it'll open a dialog to try to convince you not to open it, but you can ...

You probably need to power cycle the drive.

If your laptop's USB ports aren't powerful enough, it is fairly easy to get a high powered USB hub that will have powerful enough ports.

I've seen Billycar11 suggest a Sabrent HB-BU10 hub. Personally, I like the Plugable USB3-HUB7C. There are lots of others that will work.

Please copy & paste the MakeMKV log into a post on the forum.

Does your drive have its own power supply or is powered via a powered USB hub or is powered solely by the computer's USB ports?

I've seen people on the internet mention a bug with external drives doing weird things on macOS if they're only powered by the Mac's USB ports.

I use a Mac and that does not happen to me.

Is your computer going to sleep?

The forum can't help you with finding an old registration code. The typical advice is to email support@makemkv.com.

Please also email the dump file to svq@makemkv.com.

In the interim you can also try the Public KeyDB. https://forum.makemkv.com/forum/viewtopic.php?p=176733#p176733

As weird as it sounds, I find that sometimes my optical drives behave better after they've been power cycled. If cleaning the disc doesn't help the next best suggestion is to try a different copy of the disc. Or, try the same disc in a different optical drive. I have multiple drives and when a disc ...

What kind of disc did you try in the optical drive? Did you try more than one?

New blu-rays are likely to be AACS v82, which I think at this point still requires a LibreDrive enabled drive.

Older blu-rays or DVDs are likely to work however.

Mechanical hard drives, like most other computer components, are in very high demand these days. SSDs are great, but the world keeps a lot of data that doesn't have to be accessed that fast. Earlier this year (in January I think), Western Digital announced that they'd already sold their entire produ...
