My above connectivity issue is closed. My iPad, running Audirvana Studio remote, connects perfectly to my Apple MacBook 12-Core CPU computer running Audirvana Studio. I use the iPad to control the computer App because it is faster and easier for me to use. I have no issues!
BTW, the Audirvana Studio App’s interface is outstanding. It is very easy to use, has many sorting options and is fairly intuitive to use. Most important is my sound quality is excellent. I have not used the App’s audio settings yet because I need more time to understand them and how they work.
