I am brand new to mp3tag. Installed on Mac using inbuilt Wine shell. Instantly ran into the 'file cannot be opened' problem when I try to save a change to a music file's tags. Looked up the problem and see it is widespread and common. Also see that the solutions seem to be Windows-specific and not applicable to a Mac environment.
I am trying to edit files on a NAS by the way.
Thought I would give a bit of feedback to the mp3tag owner that this sort of issue makes a program seem 'buggy'. I am trying to do the #1 most basic task. If I have to wrestle and research to get this to work, my enthusiasm drains and I am not keen to use your app.
But if there is a simple solution then let me know (and maybe explain why I have to do it instead of having the program work more smoothly).
Otherwise, sadly, I will move on as life is short.
