Mac and No Translation
This applies to all Mac versions post Mac Sierra, and all MXWendler versions
You want to switch the Translation on, to use the software in German but it does not work.
Under new versions of OSX, Gatekeeper dislocates unsigned applications to random paths on start resulting some issues.
You need to disable the App Translocation function of MacOS Gatekeeper. Please follow this troubleshooting: Mac Sierra 10.12 Disable App Translocation
