ndtrack prompt after macbook was upgraded from highsierra to mojave What shall I do to address this ndtrack issue? I did some research online but didn't find anything particularly useful.
This is actually a feature of of Mojave. It recognizes that the software you have installed on your Mac "ndtrack" will not work if you upgrade your Mac to (currently in beta) macOS Catalina.

You should seek out an updated version of ndtrack before you upgrade to macOS Catalina.

If you have no current intention of upgrading to macOS Catalina (the final version will likely be released in the Fall) then you can just ignore this warning. But this should be updated before you do that upgrade as it will no longer work after the upgrade.

Other than that you can ignore the warning.
