“Fatal Error Occured” with MacOS 15.4 Developer Beta 1

Unfortunately, Beta 2 doesn't correct the issue.

Damn. I was just going to suggest everyone hang on a half hour while I updated.

Apple locked down a LOT of things in 15.4. I'm spending almost as much time in privacy and security settings as I am using apps for the moment.
As a few others have said, this is a newly-locked access route that was previously open.
Apple locked down optical device access somewhere that was open before.
same access problem a few other apps, including VM and translation apps.

It's odd that the MakeMKV-alternatives still work. They're just not as good as MakeMKV. Looking at you AnyMP4.

In the notes that came with 15.4.1 release Apple have made significant changes to all their SCSI handling procedures. Did anyone notice that their DVDPlayer App has disappeared and replaced with a "Viewer"?
Like most I now use the MakeMKV on a different Mac which has an Intel processor and it works fine.

Beta 3 does not correct this. Has anyone heard from the MakeMKV devs if they're looking into the issue?

Hey,
I have not heard from Apple nor the developer. Beta updates should come weekly now.

Thanks!

Given the comment above about the changes to SCSI protocols, it would seem this is a problem that the MakeMKV developers need to find a solution to. I sort of wish they would chime in here and give us, at least, a "we're looking into it". Fortunately I have an older MBP that runs MakeMKV for now.
