Apple ha puesto a disposición de los usuarios macOS 10.13.2 High Sierra, una actualización de mantenimiento a la que acompaña iTunes 12.7.2.

macOS 10.13.2 High Sierra puede considerarse como una actualización de mantenimiento y Apple recomienda su instalación ya que incluye mejoras en la estabilidad, rendimiento y seguridad del sistema. Las notas específicas que acompañan a la actualización indican que:

  • Mejora la compatibilidad con determinados dispositivos de audio USB de otros fabricantes.
  • Mejora la navegación de VoiceOver al visualizar documentos PDF en Vista Previa.
  • Mejora la compatibilidad de las pantallas braille con Mail.

Adicionalmente, para empresa, se han realizado los siguientes cambios:

  • Mejora el rendimiento cuando se utilizan las credenciales almacenadas en el llavero para acceder a sitios web de SharePoint que utilizan autenticación NTLM.
  • Resuelve un problema que impide que la Mac App Store y otros procesos invocados por Launch Daemons funcionen en redes que utilizan información proxy definida en un archivo PAC.
  • Si cambia la contraseña de usuario de Active Directory fuera de las preferencias de Usuarios y Grupos, la nueva contraseña ahora se puede usar para desbloquear el volumen de FileVault (anteriormente, sólo la contraseña antigua desbloquearía el volumen).
  • Mejora la compatibilidad con los directorios SMB cuando el punto para compartir contiene un símbolo dólar en su nombre.

Las notas al respecto de la solución de problemas de seguridad ahora hacen referencia no solo a esta actualización, sino también a las actualizaciones Security Update 2017-002 Sierra, y Security Update 2017-005 El Capitan, que se ha publicado ahora junto con macOS 10.13.2 High Sierra

    Hola, al intentara actualizar me da un error tipo “osinstall.mpkg no se encuentra o esta dañado”…
    Me pasó lo mismo también en la última actualización, creía que era fallo de esa en concreto, pero está claro que es algo de mi sistema…
    Alguna idea de como repararlo?

    Gracias!
