I've ripped a few BD's without issue on Mavericks, but keep in mind I'm using a beta OS.

That said, is anyone else experiencing a crash when trying to rip Jack the Giant Slayer?

Apparently it's a Mavericks issue. Although I did a few reboots and saw the same result, powering down completely, and powering back on resolved it and it ripped successfully.

I did disable the App Nap feature for MakeMKV though, which may have also resolved it.
