Je déconseille l’achat de l’adaptateur C2G (29326/89052) de Legrand : Thunderbolt (USB Type-C) vers Ethernet . Il ne fonctionne pas sur mon Mac : MacOS : 10.13.6 ( High Sierra ) .

Site : https://www.c2g.com/uk/product/89052/usb-c-to-gigabit-ethernet-network-adapter#description .

Driver : MACOSX driver

Voici ce que j’ai dans dmesg quand je connecte l’adaptateur :

Thunderbolt PCI – LS=0xd043 LC=0x0040 

Quand j’ouvre une console et que je tape : « kextstat | grep com.asix » , le driver n’est pas visible.

Si j’essaye de lancer manuellement le drivers :

$ sudo kextload -b com.asix.driver.ax88179-178a
com.asix.driver.ax88179-178a failed to load - (libkern/kext) system policy prevents loading; check the system/kernel logs for errors or try kextutil(8)

Si j’essaye d’avoir plus d’explication :

$ sudo kextutil -b com.asix.driver.ax88179-178a

Misère.

Mon installation :

Ma version de MacBook Pro : On peut voir que c’est en USB 3.1 : AX88179 :Quand on regarde l’extension, elle est présente :Mais cela n’apparait pas dans les cartes réseaux disponibles : Mise à jours :

• SOLUTION : J’ai autorisé le développeur « WEI LU SU », et j’ai relancé le Mac … et cela a fonctionné. C’est très professionnel de mettre le nom du développeur….

En résumé :

La documentation est donc mal faite, car il n’est pas facile de voir le lien entre WEI LU SU et LEGRAND …

… Or why not say that it fails because of SIP ?

When I see the logs /var/log/install.log in « Safe Mode », I see this command newfs_hfs -J -U 0 -G 0 -v Recovery HD /dev/rdisk0s3 :

But this command works only without SIP ?!
So the best way (in my opinion), before launch this command (newfs_hfs) is to do « csrutil status ». If the status is disabled, so it’s ok. But if not, OPEN A WINDOWS AND WRITE  » Please boot on recovery OS, and disabled the SIP « .

It’s impossible to understand this error for normal user !!!
