Hi!
we are sail with MacENC and iNavx more than 10000 miles, and generally very happy :-)
But, one small problem could be some time BIG :-)
I saw this problem only when MacENC managed GPS position, but with 3 different Mac and 4 different GPS (including Garmin) connected over USB, NMEA or Bluetooth ...
what's happens - some time (look at the first picture) - position for 1-2 seconds move in any direction, it could be from 10 to 500 miles.

minor problem - your tracking data about distance, speed and etc wrong.
but!!! last trip - we found force 9 storm with gusts more than 50knt, with 2 different, in-depended forecast 20-25knt!!! :-)

We found it on big sail, and can't furl it back! we have just one choice - turn downwind and pray :-) 9 hours until wind slow down and change direction.
unfortunately on the our way - traffic separation scheme with lot of ships. at this moment understanding information from AIS - VERY important ... but if exactly at this moment You position moved to centre of Sakhara ... You are in big trouble :-)
May be somebody saw similar problem?
