Turning off annotation did speed things up. Oddly, I've tried that before without any effect in a previous version of MacENC. The track file does not like to turn off. I've unchecked it and restarted only to see the track line being drawn again. It does disappear until I quit the program if I leave it unchecked.
I have a large and ever growing annotation file. Charts need lots of annotation in the Aleutians. I wish there was some faster running way of adding data to cover all the gaps out here.
I don't think my autopilot can send out any NMEA data. I just went out for a day and the program was redrawing charts noticeably faster, but I continued to get faulty data and no data alarms. The strangest behavior is a sudden 40° turn hard to port, then after about .1 miles of cross track error builds, it will lurch back hard to starboard and return to the original track. That never happens on autopilot. Only the nav setting causes it.
There is no way to predict the lurch off course and back. It may happen twice in an hour, or only once in a day.
