As of September 24, 2018, Apple has released macOS High Sierra (version 10.14).
ClueTrust is unaware of any problems with the current shipping version of Cartographica (1.4.8). All functionality tested is working and we have not experienced any issues with internal testing.
In addition, we've created a new beta of LoadMyTracks that addresses some recent issues with some devices and versions of macOS.
Please make sure that you are using the most recent versions of Cartographica (1.4.8) or LoadMyTracks before reporting a bug when running macOS High Sierra.
