macOS Input Source – Fix Adding Custom Input Not Working

Try this fix which Apple published when the keyboard viewer and character viewer used to disappear in 10.5:

Well, I managed to almost get it working by going to /Library/Dictionaries and rename Oxford Dictionary of English into something else. Then Spotlight started showing the results from dicts in Dictionary.app.

However, this is a rather kludgy solution for me because:

1. You have to Press Cmd+L in order to view translation, and there is no way to move 'Definition' up in Spotlight order
2. After I restarted my Mac, my Spotlight started to display result from another built-in dict, Oxford Thesaurus.

I guess, you could just remove all dictionaries that you do not use. Anyhow, maybe it could be of some help for you.
