Well I followed the instructions in the setup manual - driver, software, etc. But the interface didn’t show up in System Settings or Garageband.
Then I started searching for possible problems.
First YouTube video the fellow says he wasn’t going to use the instructions - just plug and play - and gets straight in.
Now I’ve spent a couple of hours trying different things offered as advice on the web, but all I have is a box with lights on and no connectivity.
So if anyone has words of wisdom you will make a man - who should be celebrating his 32nd anniversary - very happy…
