Does the mac version support mkv tagging? I'm unable to open an mkv in the beta version I installed last week.
The freshly release version 1.0 of Mp3tag for Mac doesn’t support MKV.
It’s a very complex format and brings with it also the need to support chapters in a reasonable way. At the moment, I’m not 100% happy with how the Windows version is handling chapters and would like to improve the situation when tackling this for the Mac version.
It’s on my list for a future release.
