MakeMKV new version v2.0.0 (20.9.2026)

[Ferrett1983]

I seem to be having a problem opening a blu-ray disc up on this version. It tries to open disc but then hangs/crashes.

Same. And I get this:

Ok, I had some weirdness on my Mac Mini.. I'm running MacOS 27.2 Beta. With 1.8, I can see the Blu-Ray drive just fine. When I installed 2.0, I could not.

And a number of apps crashed. (firefox, Brave got "stuck", etc..) Makemkv also wanted me to enable application management, something 1.8 doesn't.

Anyone else seeing "issues"?? I removed it from my Mac. I'll stick with 1.8 for now.

MacOS is vary particular about versions. Have you specifically enabled 2.0.0 to run? Otherwise, it will consider it a danger to your system, and refuse it.

I have the same issue on linux compiling it myself... 1.18.4 works fine but 2.0.0 crashes when trying to open the disc or files...

1.18.4 works fine but 2.0.0 crashes when trying to open the disc or files...

Same here...

EDIT : The issue seems to come from the main makemkvcon binary, not the GUI.

Looks like it's fine here. BD's and DVD's works fine. MakeMKV-2.0.0 (Linux) from sources.

It doesn't work for me with an Ubuntu-based distro. Same with my Arch distrobox.

[Ferrett1983]

I'll carry on using 1.18.4 for the time being until the issues resolved.

I'll also add a report that v2 gives me the same error on a Windows install on Windows 10 with an BP60NB10 LG USB drive. Reverting back to 1.18.4 with the same disc and drive works with no errors.

Same, Fatal Error, Windows 10, reverting back to 1.18.4.

I have a MakeMKV implementation on my UGREEN NAS, naturally it's the Unix version.

MakeMKV v2.0.0 linux(x64-release) and I'm having the same issue, where I can open DVD ISOs, but Bluray/UHD ISOs result in a "Fatal Error" and subsequent crash.

Has anyone patched the Unix version yet? Is there a way to revert back to the previous version?

Linux: the "SDF auto" hang reported since 1.17.8 is still present in v2.0.0.

Setup: MakeMKV v2.0.0 linux(x64-release), Debian 13, kernel 6.12. Drive HL-DT-ST BDDVDRW CH08LS10, firmware 1.00 (USB SATA bridge).

Symptom: with any disc inserted (Blu-ray or DVD), makemkvcon never gets past "Scanning CD-ROM devices". One thread spins at 100% CPU in pure user space, with no drive I/O. The debug log ends at:

Code: Select all

SDF auto v0a6: HL-DT-ST_BDDVDRW_CH08LS10_1.00_20090115123456_<serial>

macOS is fine: the same drive, bridge and disc work with 2.0.0 on macOS (same SDF v0a6), which writes ~/Library/MakeMKV/dump_FW_<id>.tgz.
(macOS 26.6.2, Apple silicon / arm64, MakeMKV 2.0.0)


Workaround: copying that dump_FW_<id>.tgz into ~/.MakeMKV on Linux fixes it: the Blu-ray scans and decrypts normally. So the Linux build appears to loop while generating the firmware dump.

Happy to test a fix or send more logs.
