“Fatal Error Occured” with MacOS 15.4 Developer Beta 1

[nicholfd]

As a developer myself; I have two thoughts.

First, this looks intentional beyond the obvious, I believe they are trying to get ahead of a firmware attack that is reported but not generally not yet covered and as far as I can tell not in the wild yet.

Second: this change has broken most but not all ‘rippers’. Without being completely obvious the one from CN and the one from MY both still work. (Neither hold a candle to the ability of mMKV).
So does Daemon Tools.

I sincerely doubt this is intentional to this type of software.

Every piece of software of this type, for macOS, definitely uses some open source libraries for cross platform support. Apple uses (and documents) a lot of open source libraries within macOS. I suspect that a common piece of open source software/library is being used by the apps of this type that are now broken, and that Apple has deprecated it or moved on to a different version that theses apps weren't prepared for..

FYI: As a temporary get around, I'm running a Windows 11 Virtual machine using Parallels. Makemkv for Windows works fine in that environment. Just a few extra steps. Definitely prefer to run it native on the mac.

I've tried this as well, but I keep getting the occasional SCSI error, and 4K's will not read whatsoever.

Everything was fine in the MacOS version.

Has anyone been able to make it work for 4K's using Parallels?

Same problem continues with the official 15.4 release.

Hi all

Having this issue too. Ripped a DVD before installing 15.4 (released today) and it worked fine. Tried to rip another one after I updated my Mac and I am getting this issue. Panicked thinking I had broken my computer!

Luckily I have an old laptop kicking about that I can use to rip in the meantime but it's not ideal.

Hoping the devs can look into it soon.

Same issue here just upgraded to official 15.4 and now Make MKV has fatal error, working perfectly today before upgrade.

The Dev really should have issued a fast update with a warning banner notifying the user of this problem. I suspect that this forum is going to get rather busy over the next few days.

I am also having this issue since the update from today. I actually need to use this software soon. I hope you can fix this ASAP

It would be appreciated if the developer, who people have paid money to for this software, could at least issue a statement.

Has anyone who has updated to 15.4, I'm still on 15.3.2, tried running MakeMKV in Parallels?

The updated version for 15.4 will be available in a couple days.

[DavoBR]

The updated version for 15.4 will be available in a couple days.

Thanks Mike
