Error on run

[brijazz]

Just installed DV7toDV8 (app, not script) on an older Mac, running 10.13.6. On my first run, I get this error:

Any suggestions?

mkvtoolnix dropped support for macOS 10.13 in v42.0, so I think you need to install v41.0 and then use the option in the DV7 to DV8 Settings app to enable Use system tools.

I would recommend:

• Install Homebrew
• In Terminal:
  • Install mkvtoolnix: brew install mkvtoolnix
  • Install dovi_tool: brew install dovi_tool

If you can get those to compile and install for macOS 10.13, you should be able to enable the option to use them in the Settings app, approve the security controls, and hopefully be good to go.
