Apple - Is there a way to set a Finder Shortcut for 'Tags…' in macOS 10.14 Mojave?
In Finder, go to preferences, then Tags. Remove all favorite tags, and the shortcut should work.
I got it to work again!
In Finder settings, remove all the favorites in tags. Then go to a file and manually click Tags...
from the menu bar, type in a tag and press enter. Next time the shortcut works, on all other files too.
