I haven't had any issues in the past until today, setting up my Mac mini and installed Kontakt 6.3.2 & Kontakt 6.5.0

Went to add libraries and usually they are imported as usual...however today It shows them as imported in Kontakt 5.6.0 but when I open Kontakt 6 none of the libraries are there...there isn't even an xml files in application support / service centre

Any ideas what could be causing this

I am on Mac mini, 16gb, 2TB quad core

 

Are you on Mojave+? And do you get a .tmp file appear on your desktop after?
And which libraries?

 

I am on high seirra, I don’t notice any .tmp files on the desktop

I just thought it was some libraries but it would appear it is all of them

 

Check to see if you using the same id numbers

 

This happened to me 5 days back , i fixed it.

Possibly:

Native access was used by you recently and the folder permissions were changed ,
this can also help if you notice an sc3.temp file automatically created on user desktop.

it's just that you as a user don't have the rights\permission to add the newly made .xml to Service Center Folder.

On a mac all you have to do is change Service Center folder permissions and add yourself as read and write owner.

on my mac i changed it mac HD>Library>Application Support>Native Instruments>service center

Then sc3.temp is never created on desktop, and the library that shows up on Kontakt 5 and Kontakt 6

hope it helps.
