Hello,
I use Mac OSX 10.11.6, MacEnc 8.75 and the BU-353-S4 USB GPS receiver on my MacBook Pro mid 2009 with the Prolific Driver PL 2303 and have big problems.

The program freezes regularly as soon as the Mac goes to sleep and is reactivated again. Then the program does not work until the Mac has been restarted.

The same problem occurs as soon as I want to switch to another program during the MacEnc use.

Besides that, tracking shows wrong positions all the time.

What can I do?
I've added some screenshots of the console, which may help to locate the error.
I need urgent help.
I already send an email to gpsnavx@mac.com. Without any response so far.

Best regards

Please ensure that you have installed the Prolific driver correctly for El Capitan.

See this article on the Navigation Mac website:
Installing Prolific driver in El Capitan

Also, contact the new developers of iNavX and MacENC by clicking the Support tab on the new iNavX website:
iNavX.com

Please note that there is a new, signed version of the Prolific driver for macOS Sierra. This no longer requires disabling the System Integrity Protection before installing the driver:

Prolific PL2303 V.1.6.1 for USB GPS
