This is a bit late, but I finally have a build of MKVToolNix for MacOS X available.

Being that my development system is quite outdated, and will not manage Tiger, it has, and will be built for MacOS 10.3, with a G3 target. It should work ‘just fine’ with MacOS X 10.4. Feedback would be greatly appreciated.

I will slowly rebuild my build system for each tool I have previously supported, and as I manage to do so, the applications will be placed back into the Current Software section.
