Dorico 3 Elements doesn't recognize Kontakt 5 or 6

Today I got a clean MacBook with 10.14.6, installed Dorico 3 and then Kontakt 5 and 6 with the latest version as provided by Native Access. Then started Dorico and both Kontakts appeared.
Kontakt 5 has here with me version 5.8.1(R43) and Kontakt 6 is v6.1.1 (R66). What version of the plug-ins are you guys running?

Also, I want the mac users to try the following:

  • Open a Terminal window and do

cd /Applications/Dorico 3.app/Contents/Applications/VSTAudioEngine3.app/Contents/Components/VSTPlugManager.bundle/Contents/Resources

and then

./vst2xscanner -p /Library/Audio/Plug-Ins/VST/Kontakt\ 5\ 16out.vst

and if you have Kontakt 6 then also

./vst2xscanner -p /Library/Audio/Plug-Ins/VST/Kontakt.vst

What does happen?
Here with me, after a few seconds it spits out following text:

<?xml version="1.0" encoding="UTF-8"?>

/Library/Audio/Plug-Ins/VST/Kontakt 5 16out.vstInstrument5653544E694F376B6F6E74616B7420355653454E694F376B6F6E74616B742035Kontakt 5 16outNative Instruments GmbHVST 2.45.8.1.00001103

With the lines above you just invoked the plug-in scanner manually. This is exactly that, what Dorico resp. the audio engine also does for every plug-in that it finds in the search path. So it is the output of this, that decides if a plug-in gets blacklisted.

On Windows this works similarly, but putting in the paths is more complicated and you have to know what you are doing.
