Hi Matt,
Did you try using /Applications/Ifeffit/bin/feff6 as the preferred feff executable in Artemis? That's what the error message was suggesting you try.
I had inserted the /Applications/Ifeffit/bin/feff6 path instead of just feff6 in the Artemis preferences, but the error persists
Can you verify that you have /Applications/Ifeffit/bin/feff6?
I do have it there.
