I have a verified EchoLink account which I am able to use flawlessly on my iPhone. Yet, I am unable to get EchoHam (version 2.14) to work on my MacBook Air running High Sierra (macOS 10.13.6). It installs without a problem but will not connect to any station, even though I have read and tried all the suggestions I have found in the documentation. So after being a ham for over 50 years, I find myself in need of an "Elmer" who knows the secrets. What say?
