多网卡在 Mac 系统的问题
当前是这样
> ip route
default via 30.5.104.1 dev en0
30.5.104.0/21 dev en0 scope link
30.5.104.1/32 dev en0 scope link
30.5.109.155/32 dev en0 scope link
127.0.0.0/8 via 127.0.0.1 dev lo0
169.254.0.0/16 dev en6 scope link
169.254.0.0/16 dev en0 scope link
198.18.0.0/16 dev en6 scope link
198.18.166.54/32 dev en6 scope link
198.18.255.252/32 dev en6 scope link
224.0.0.0/4 dev en6 scope link
224.0.0.0/4 dev en0 scope link
255.255.255.255/32 dev en6 scope link
255.255.255.255/32 dev en0 scope link
预期是这样，注意 en0 和 en6。

进入系统偏好设置，网络，左下角的齿轮，更改服务顺序，拖动wifi到有线网卡上面就可以了
