Ethernet non funziona su MacBook pro retina 13

La mia connessione Ethernet non funziona sul mio computer (metà 2015).

Ho già riavviato, cancellando i file "NetworkInterfaces.plist" e "preferences.plist" nella cartella "/ Library / Preferences / SystemConfiguration". Ho aperto una finestra di terminale, dando questo comando

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder; say DNS cache flushed

e poi ho riavviato di nuovo.

Ma niente sembra funzionare.

Qualche idea?

Qui do lo schermo delle informazioni di sistema, è italiano, mi dispiace per questo. Comunque dice che nessun driver ethernet è installato (il problema potrebbe essere con questo?) E la scheda Thunderbolt dice "nessun dispositivo connesso" anche quando l'adattatore ethernet è lì. Ho anche provato a collegare un adattatore VGA per collegare un monitor e questo funziona, quindi non è la porta del fulmine.

Se è recente, potresti essere vittima di un brutto aggiornamento di protezione da malware da parte di Apple. Hanno pubblicato un articolo di supporto che spiega come verificare se questa è stata la causa e come risolverlo.

First, check your version number

While pressing the Option key, choose System Information from the Apple menu.

Expand the Software section and select Installations.

Click the Software Name column header to sort the list alphabetically.

Look for “Incompatible Kernel Extension Configuration Data.” If the most recent version installed is 3.28.1, follow the steps below.

If you can connect to Wi-Fi, follow these steps to update to version 3.28.2

Open the Terminal app.

Enter this command to update to the current version of the “Incompatible Kernel Extension Configuration Data” kernel extension: sudo softwareupdate --background

Quit Terminal and restart your Mac.

If you can't connect to Wi-Fi, follow these steps to update to version 3.28.2

Restart from OS X Recovery by holding down Command-R while your Mac starts up.

Select Disk Utility from the list of OS X Utilities.

Select your drive from the list of internal drives in the sidebar. The default name is “Macintosh HD.” Your drive might have a different name or location, if you renamed or moved it.

If the drive name is dimmed, your drive might be protected by FileVault. Choose File > Unlock from the Disk Utility menu, then enter your FileVault password.

Choose File > Mount in Disk Utility to mount your drive, if it's not already mounted.

Quit Disk Utility.

To make it easier to enter the command shown in step 9, you might want to copy it from Safari:

Choose Get Help Online from the OS X Utilities list, then go to support.apple.com/kb/HT205956.

Select the command in step 9, copy it, then quit Safari before you continue to the next step.

Choose Utilities > Terminal to open the Terminal app.

Type or paste the following command as one line in Terminal, then press Return. Replace Macintosh HD with the name of your hard drive, if different: rm -rf "/Volumes/Macintosh HD/System/Library/Extensions/AppleKextExcludeList.kext"

Now complete these steps to update to the current version of the “Incompatible Kernel Extension Configuration Data” kernel extension:

Quit Terminal.

Choose Restart from the Apple menu. After your Mac restarts, your Ethernet connection should work.

Open Terminal and enter this command: sudo softwareupdate --background

Quit Terminal

Choose Restart from the Apple menu.

Alternatively, if you confirmed that your Mac has Incompatible Kernel Extension Configuration Data version 3.28.1, you can also restart your Mac into OS X Recovery mode, then select Reinstall OS X. You can reinstall OS X on your drive without reformatting it.
