ABC plugin not working on macOS 10.14 or later
ABC input plugin is not working on 18.104.22.16837.
Since the latest update the ABC input plugin is not working. I have tried reloading the plugin and reinstalling Musescore, but neither has worked. I use ABC files from several sources, all of which have been working fine until this latest update. I know this happened back in 2018 but was resolved, but it seams to be back again.
