Hi Christer, You want the FTDI VCP Drivers, not the D2XX. As Jack mentioned, the FTDI drivers are now provided by Apple and are included in all versions since OS X 10.9. You should uninstall the D2XX drivers.
Also try deleting the KX3 Utility app, and it's preferences file, and download again from the Elecraft web site and reinstall. The preferences file is located in the /Users/your_user_name/Library/Preferences folder on the Mac. The Library folder is usually hidden. A quick way to get there is to click the "Go" menu in Finder and press the "option" key. The Library folder will then appear in the Go menu. The KX3 Utility preferences file is named "KX3UtilPrefs".

Yes I have the D2XX drivers and gone through the installation guides several times, as well as numerous restarts in between. That in advance for usable advice 73 SA0PAL, Christer ”Worry is like a rocking chair.
