version 1.18 is now out for Mac OS which seems to have stopped the fatal error crash

Ouch. I swear it was tested....
This is a bug, will post the update shortly.

UPDATE: 1.18.0 has a bug - the program crashes when it is unable to open BD disc, and for most UHD discs. 1.18.1 is coming...

Great to hear, can't wait

Thanks Mike

I can still not rip my movies still getting this error.

Hi,

With the update 1.8.0 the application starts.

But now when I try to read the disk MakeMKV crashes again with a Fatal Error right after it loaded the content hash table.

Right … 

I’m getting similar issues, as well.

The updated copy of MakeMKV will happily back up a 2k disk: or turn it into a series of MKV files.

But, when a 4k disk is inserted, it starts to read a 4k disc: then shows a fatal error.

I don’t know how to export the logs: otherwise I would include them.

(If it’s any extra help, it *sounds* like the 4k disk is spinning up: but not stopping spinning. The 2k one, by contrast, spins when inserted: then stops. These are in two different Panasonic BDR-UD04’s. I don’t know if that helps.)

In still have this error when i updated mac os this week , how can this be solved . i am very frustrated about it.

After updating to MakeMKV version 1.18.0 to fix the macOS 15.4 bug that crashes MakeMKV, I am still having problems. I tried multiple different Pioneer USB-C drives that worked fine previously. I restarted macOS and reloaded my test disc, Tommy Boy (1995) in UHD. I deleted all the MakeMKV data files in Library/MakeMKV.

The application loads a little strangely, somewhat slower than before. I am ripping Tommy Boy now, but every couple of minutes in hangs for about 30 seconds where nothing is ripping but the timer is still going. Then oddly, it resumes. Fingers crossed now that it will finish, with about an hour to go.

I’m looking forward to that … !

Is this bug only for MacOS? I am having similar issues on Windows with version 1.17.9. Today out of nowhere, I keep getting fatal error occured but only on UHD movies.

Bug was universal (

1.18.1 is out.

So far so good, the Serenity UHD disc is working as I type with version 18.1.1. Thank you for the rapid response here!

Well...at least I could rip my Blu-rays.

Looking forward to the .1 release that fixes this new issue.

See 2 posts above yours. 1.18.1 is already released & resolves the UHD issue (and another issue).
