Tengo una mcBookAir modelo A2179, y compre un hub multifunción con conectores USB-c y HDMI, mas dos USB 3.0,


ISSUE: cuando quiero conectar una tarjeta de red USB, después de desconectar el hub repetidas veces en el dia (para ir a juntas a otros salones), finalmente la Mac ya no reconoce ningún dispositivo USB. El display externos sigue operando.


Para restablecer la funcionalidad la Mac requiere reiniciar desde cero (reboot) y los puertos se rehabilitan entonces.


Mac model: A2179, con Catalina instalado 10.15.7 8Mb RAM

The USB-C adapter should include a PD port that allows pass through of your power for at least 100W. If this translation is difficult to understand, please post to the Spanish community.


El adaptador USB-C debe incluir un puerto PD que permita pasar su energía por al menos 100W. Si esta traducción es difícil de entender, publíquela en la comunidad española.
