Mac OS 26 Beta

Post by asr101 »

Has anyone been brave (foolish) enough to update to the beta of Mac OX 26 (Tahoe) and test MakeMKV on it?

Thanks for any responses.

I installed the macOS Tahoe 26.0 Release Candidate that was released on September 9. So far everything seems to be working normally using MakeMKV 1.18.1. I have used it on only one disc that was a 4K Blu Ray, and that one saved successfully.

Yup it's working just fine with the RC! Only detail I have noticed is the icon doesn't conform to the new design language.

Thanks for your updates! I was too busy to set up an external boot to test it this time around.

I just now tried it, and neither version 18.1 nor 18.2 would load. I got some language about make mkv being downloaded from the Web and could damage my machine, yadda yadda yadda, but I couldn't bypass it as I used to be able to do. I'm going to try install an earlier version of MacOS and see whether that works. If anybody knows of any work-arounds, I'd be most appreciative to learn then,

Presumably this method still works: Gatekeeper in macOS X 15 Sequoia

hi - i am running 26.1 and cannot get MakeMKV to open; I get the icon bouncing issue. When prompted for my password through GateKeeper, it won't even accept that. When trying to do the xattr command in terminal, the command completes, but MakeMKV still won't run. I have tried installing back to 1.17.0 and still have the issue. Has anyone had any luck here?

Hi you might want to raise this with Asmcom towards the end of this thread
viewtopic.php?f=20&t=19387&hilit=Asmcom&start=1425

He mentions Tahoe 26.1 working OK
Cheers
