Did you try following the instructions @MadHun posted above?

Those instructions used to work for me. But when I followed them with Emacs 27.1, Emacs refused to start. Chris Farber, the author the blog post referred to earlier, posted a workaround in a comment.

Is that in Finder (i.e. Finder window in /Applications/, or the Dock?)

That's in the Dock.

I've noticed that

tell applications "Emacs" to activate

is a bit laggy compared to the normal "Launch Apps / Files" action. Sometimes it takes a couple of seconds to change focus.

Could you please test what happens if you try launching Emacs from Finder by double clicking the app? I suspect you won't get focus in this situation either (i.e. a little Emacs / Catalina bug).

In fact, that works as expected. Clicking it the first time launches Emacs, and clicking it subsequent times switches focus to Emacs.

If so, perhaps instead of a Launch Apps / Files, you could use a Run AppleScript in Alfred with something like:

 

tell applications "Emacs" to activate

 

Thanks, that works! That's good enough for me.

I have the same problem. I have a workflow that used to launch Emacs if it wasn't open, and switch focus to it if it was open:

This worked on Mojave. On Catalina, the shortcut launches the app if Emacs isn't yet running. But if Emacs is running, the shortcut doesn't do anything.
