Thank you, Steve. I will investigate the JAVA app on your link as time permits. I am really a computer dummy when it comes to anything beyond using ordinary Mac and Windows applications.
For the time being, I will experiment with an application, DSP Radio, which I downloaded earlier today. This was written for Mac OS and opens with no trouble on my MacBook. It is freeware from Sebastion Mrozek/DL2SDR.
After I get the SoftRock built, I'll post my success or failure.

UNfortunately not many of us are MAC gurus Ed, BUT Steve has been involved with MAC for a very long time.
You will have to take some extra steps to get it up and running.
