Gracias por la respuesta.
Las tres aplicaciones de Apple se Cierran inesperadamente, pero el resto funciona perfectamente. Si arranco en Mac en Modo Seguro, las tres aplicaciones Notas, Mensajes y Textedit) siguen cerrándose inesperadamente en uno ssegundos después de arrancar.
Únicamente funcionan con un usuario Estándard, pero no como usuario Administrador.
Le adjunto una parte del log del sistema después de ejecutar la App Texwrangler, que no es de Apple y parece da unos problemas similares:
