I've an issue with Cura profiles and a MacBook updated to latest osx. I've followed this site instructions and all YouTube video related.
I've deleted Cura, installed 4.6.1 and profiles no working because during the import I receive the message "configuration error".
Finally I've installed 4.5, copied all files in resources folder inside the application, then the same files inside /Library/Application Support and finally imported the profiles, and it worked great. I could see all 3DNexus profiles and i've tried also to slice successfully a file. After I close Cura, and I reopen it, all 3DN profiles have disappeared and if I go to Preferences/Profiles, I see them but if I click one of them there is written "Not Supported". So I've tried All and I don't know what to try more
