Is that it ? There's no other way ???
Unplug it.
Now, we're getting somewhere (but great ideas, guys!). So Macvanguy, I opened Network, there is 'configure IPv6' (not 4 here) yet no 'off'.
So. . .
you just have to create in Network preferences a new location called for example "ETHERNET OFF".
Configure IPv4: off
Then just select it in a menu App like iStat Menus.
that's all![]()
