I’m typesetting in Italian and thus using 

\mainlanguage[it]

I suspected something went wrong, and in fact I see in terminal:

But I get

system          > 'cont-new.mkiv' loaded
(/Users/andrea/context/tex/texmf-context/tex/context/base/cont-new.mkiv)
system          > files > jobname 'attiZaffiri', input './attiZaffiri', result 'attiZaffiri'
fonts           > latin modern fonts are not preloaded
languages       > language 'en' is active

What am I doing wong?

Best
