No. The Mac installation never gave me the standard drag and drop of the icon to the Apps folder. Thanks for the reminder there.
So I reinstalled Electrum but this time opened the Apps folder in Finder then physically draged the Electrum icon across the desktop and
dropped it in the Finder window.

Now when I attempt connection from testnet server to wallet I still get a wallet error.  This is because in the script line execution of

open -n /Applications/Electrum.app –args –testnet

now finds the Electrum.app but now says that -args and -testnet do not exist.
I'm curious here if any one out there has gotten this to run on MacOS?
Getting closer I think.

Has anyone here ever heard of the Gestapo? Rape of Nanking? How about ISIS?  I could go on but the only thing that would prove is there can be mass amounts of big-time evil in the world.  This can occur at nearly anytime and any place.  There is only one answer that these enemies understand.  Burying your head in the sand and blaming oil, money, US or whatever will do nothing.   I would truly love to be a pacifist but my world is too filled with potential dangers.

Electrum 3.2.2 on OS 10.13. The beginners guide I have says to open a nano text editor. Insert with the following 2 lines

#!/bin/bash

open -n /Applications/Electrum.app –args –testnet

Then save the the text file.  It then appears as an electrum icon on the desktop.  Click the icon and away you go. 
The problem here is there is no Electrum.app in my Applications folder and any testnet transfer fails with a wallet error.
In fact I cannot locate anything or any directory related to Electrum or the wallet instal anywhere on the system. So I can't point
to the correct place to go for default_wallet.  What have I done wrong here?  Thanks in advance.
