Glad to hear a fix is coming, I was a bit panicked when I put in a new Blu-ray today to rip and saw an error I've never seen MakeMKV show before. :cry:

YAY! Mike, you are my hero. Have googled everything in terms with this issue ... and found out that this is not a single problem of mine (have a purchased lifetime license). Had already suspected that there was a connection with macOS, but now I am reassured that the OS is the culprit. Before the update on Monday, everything was working fine.
Thanks again for your wok. :-)

I’ve been having this issue, as well: do we have an ETA for the update?

Went to do first rip today since upgrading to 15.4, and ran into this error.

So in the grand tradition of 90's era AOL.. "Me too!"

I hope so, Mike: this is very frustrating … !

Hadn't used MakeMKV for quite some time and tried at the worst moment, just after updating all my Mac to macOS 15.4! :-)
Very good news that a fix is coming soon.

Also, MakeMKV can rip discs in a Windows VM (I fully tested Parallels Desktop and started a rip with UTM) on an Apple Silicon Mac, so for those with Windows VM, that's a (hopefully very temporary) workaround :-)

Does this work for 4K's as well?

Yes. I only tried 1 4K Blu-ray disc though. I could use the MakeMKV registration code in MakeMKV for Windows :-)
This is with Parallels Desktop 20 and Windows 11 Pro 24H2 for ARM on a Mac Studio M1 Max with macOS 15.4.
I just extract directly to a (shared) folder on the Mac side :-)

That's brilliant. Thanks so much for confirming!! :)

I sincerely doubt this is intentional to this type of software.
That was my point, Apple depreciated and partly disabled some old communications functions.

Does anyone know if we can use the MakeMKV key with the Linux version of MakeMKV?

I have an M2 Pro Mac mini for a couple of years now running a few server apps for me but lately Apple has been 'improving' their OS in rather prohibitive and non sensical ways.

We had the gatekeeper issue where we have to authorise MKV and other apps to work. Since the start of the year, Plex Synology shares over SMB have been broken and if it wasn't for some clever work around by Plex forum members, I would have thrown the Mini out the window!

Now we have this issue. I am aware Mike is actively working on it and I am sure the fix is incoming and happy to wait. I just can't help feeling with Apple and certainly Microsoft, we are all second class citizens!

I don't use iOS anything in our house hold. All the apps I use are available in Linux with the exception of a Roon native GUI version ( can run headless).

Annoying all this is...

Rant over, :(

I use Plex over a network share on an M2 Pro MacBook and haven't had any issues.

Your MakeMKV key works on any platform MakeMKV supports.
