Location of SoundFont

I cannot get the sound to play; When I open Musescore, I get a message;

"Loading SoundFont "/Applications/MuseScore.app" failed. Playback will be disabled.
Go to Display > Synthesizer and check that the file location is correct"

Having done that the SoundFont location is shown as /Applications/MuseScore.app

The file for the Soundfont TimGM6mb.sf2 is located at MuseScore.app/Contents/Resources/sound

How do I edit the Synthesizer to the correct location? I have tried clicking on the icon to the right of the location script to no avail.

My husbnd has downloaded and successfully installed the various elements with no problem.

I have uninstalled several times and re-installed, to no avail.
