Mac OS 修改ip
使用VNC远程修改IP v4会：报无效的服务器地址 BasicIPv6ValidationError
所以还是用命令吧！设置IPv4地址
终端输入：networksetup -setmanual Ethernet 192.168.31.2 255.255.255.0 192.168.1.1
对应网卡设备、IP地址、子网掩码、网关
为什么是“Ethernet” 看下面
先ifconfig查看网卡文件，如下好多网卡文件，这样问题来了、要修改那个？？？

我们可以使用：networksetup -listallhardwareports网卡设备使用的网卡文件
ptr:~ roothost$ networksetup -listallhardwareports Hardware Port: Ethernet Device: en0 Ethernet Address: f0:18:98:ee:ce:27 Hardware Port: Wi-Fi Device: en1 Ethernet Address: 38:f9:d3:1a:44:29 Hardware Port: Bluetooth PAN Device: en7 Ethernet Address: 38:f9:d3:bf:5d:96 Hardware Port: Thunderbolt 1 Device: en2 Ethernet Address: c6:00:0d:31:0c:01 Hardware Port: Thunderbolt 2 Device: en3 Ethernet Address: c6:00:0d:31:0c:00 Hardware Port: Thunderbolt 3 Device: en4 Ethernet Address: c6:00:0d:31:0c:05 Hardware Port: Thunderbolt 4 Device: en5 Ethernet Address: c6:00:0d:31:0c:04 Hardware Port: Thunderbolt Bridge Device: bridge0 Ethernet Address: c6:00:0d:31:0c:01 VLAN Configurations =================== ptr:~ roothost$
好吧，原来是 Ethernet、Wi-Fi、Bluetooth、Thunderbolt等 设备使用对应的网卡文件
因为是接网线的，所以我们修改 Ethernet 以太网就有线网卡这个。
当然也可以这样：
终端输入：networksetup -setmanual en0 192.168.31.2 255.255.255.0 192.168.1.1
我表示没有测试过
