Can you get internet by tethering to your phone? If so, the computer should sync with NTP pretty quickly, then hold to within a second while you are operating.
You might be able to force a sync by opening the Date & Time control panel in System Preferences. MacOS uses NTP by default. If that doesn’t work, I’d unlock the panel, uncheck “Set date and time automatically”, then recheck it. If you are of the shell persuasion, this will do the trick. sudo ntpdate -u time.apple.com wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 15, 2017, at 11:46 AM, James Bennett <w6...@me.com> wrote: > > I have a MacBook Pro Retina Display running Sierra 10.12.5 that I use with my > KX3 when operating portable.
