Resposta para "iPhone is showing charging is not supported with this accesory"I found that when plugging the USB connector into the MacBook Pro or the wall charger it is important not to push the USB connector all the way into the USB port. For some reason. when it is pushed all the way in, the error message "charging not supported" comes up. When I get the message I disconnect and re-connect pushing it in just far enough to connect and it works. I do not get this message with the car charger. All the best!
