有时候我们需要指定固定的mac地址上网
具体方法：
networksetup -listallhardwareports //查看当前所有端口Mac地址
sudo ifconfig en0 ether e4:ce:8f:32:51:82 //修改
ifconfig en1 | grep ether //查看是否修改成功,这里修改的是虚拟Mac,看硬件是看不出来的
demo案例：修改en8的mac地址
1、查看当前所有端口mac地址
apple@fenglolodeMacBook-Pro ~ % networksetup -listallhardwareports
Hardware Port: USB Ethernet
Device: en8
Ethernet Address: 00:0e:c6:68:7d:c1
Hardware Port: Wi-Fi
Device: en0
Ethernet Address: 78:4f:43:83:5a:5a
Hardware Port: Bluetooth PAN
Device: en5
Ethernet Address: 78:4f:43:84:d0:d8
Hardware Port: Thunderbolt 1
Device: en1
Ethernet Address: 82:c9:93:e2:54:01
Hardware Port: Thunderbolt 2
Device: en2
Ethernet Address: 82:c9:93:e2:54:00
Hardware Port: Thunderbolt 3
Device: en3
Ethernet Address: 82:c9:93:e2:54:05
Hardware Port: Thunderbolt 4
Device: en4
Ethernet Address: 82:c9:93:e2:54:04
Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: 82:c9:93:e2:54:01

===================
2、修改en8的mac地址为98:ee:cb:a3:8d:bf
apple@fenglolodeMacBook-Pro ~ % sudo ifconfig en8 ether 98:ee:cb:a3:8d:bf
Password:
3、查看修改后的en8的mac地址，确认是否修改成功。
apple@fenglolodeMacBook-Pro ~ % ifconfig en8 | grep ether
ether 98:ee:cb:a3:8d:bf
