El Maya le instale con Vue ya instalado, al desinstalar el Maya elimine el plugin y todo tipo de conexiones. Ya una vez instalado Maya metí el plugin de vue. Seguramente sea un problema de permisos, ya que Lion es muy cañero con ese tema (para instalar Vue tuve que darle unos permisos nuevos mediante batchmod). Si quieres miro eso de resetear los valores de Xstream, aunque no sé si sabre hacerlo bien.
De momento va bien la cosa, me renderiza con todo y ya no da error.
