Iphone 6+ USB si disconnette continuamente da Macbook Pro

6

Il mio iPhone continua a disconnettersi dal mio MacBook Pro; in effetti qualsiasi iPhone che provo a connettere (e con cavi diversi) non può mai connettersi ad esso.

Ho molta familiarità con la linea di comando e Linux, quindi per favore se qualcuno ha dei suggerimenti su cosa potrebbe succedere qui sentitevi liberi di inviare comandi o posizioni in cui posso provare a trovare la fonte di questo problema.

Specifiche MacBook: Sierra 10.13.3 MacBook Mid 2015 Intel Core i7 da 2,2 GHz

iPhone 6s Plus / anche se ho provato con iPhone 5 e iPhone 6 oltre a 3 cavi diversi.

L'output tail -f /var/system.log è il seguente

        Jan 25 12:21:05 MyMac PrintUITool[488]: notify name "com.apple.system.powersources.source" has been registered 320 times - this may be a leak

One of the two will be used. Which one is undefined.

Quando collego iTunes continua a fare la stessa cosa ma i rapporti di errore sono i seguenti:

dmesg stampa queste righe più volte:

    NCM Data: family specific matching fails
    AppleUSBInterface: family specific matching fails
    Apple USB Multiplexor: family specific matching fails
    NCM Control: family specific matching fails
    AppleUSBInterface: family specific matching fails

Sto cercando di creare un'app al momento quindi non essere in grado di provare su un dispositivo reale è un problema, qualcuno è riuscito a risolverlo o a trovarlo prima?
