Could this be a Mac-specific issue?
Another user has reported experiencing the same issue when he moved a working PR3 installation from a W10 machine to an iMac: <>.
Customtraxx (George?) has reported that he's used the PR3/MacBook Pro combination in stand-alone programming mode for years with no issues, so we have to assume his JMRI preferences and physical/electrical connections are (or were) good: <>
And if I¡¯m reading his earlier post correctly, he also reported that another user at his club, apparently also a Mac/PR3 user, had the same issue: <>
Can any of the developers with a Mac and PR3 look into this from the Mac side of things? I'm not a Mac user, so I'm not able to help other than pointing out the above which seems like too much of a coincidence to me. FWIW, my PR3 is working fine with JMRI.4.7.6.R570b2bc on W10.
