Sometimes I need to send my traffic to a proxy, sometimes I don't.

Currently, I have to go to the settings every time to click it.

Is there any simple way for me to switch this? For instance, use a shell command to do this.

system proxy

  • sudo networksetup -setsocksfirewallproxy "USB 10/100/1000 LAN" 8888 / sudo networksetup -setsocksfirewallproxystate "USB 10/100/1000 LAN" off / sudo networksetup -setsocksfirewallproxystate "USB 10/100/1000 LAN" on works great. – AGamePlayer Jun 23 '17 at 13:57

This can be done with networksetup.

Get all services:

networksetup -listallnetworkservices

Then with the proper service (e.g Ethernet or the name of your USB 10/100/1000 LAN adapter) enter

sudo networksetup -setsocksfirewallproxy <networkservice> <domain> <port number> <authenticated> <username> <password>


sudo networksetup -setwebproxy <networkservice> <domain> <port number> <authenticated> <username> <password>

to configure it (which isn't necessary in your case, because you already entered all necessary values).


sudo networksetup -setsocksfirewallproxy Ethernet 18080
sudo networksetup -setwebproxy Ethernet 18080

To simply toggle it on or off use:

sudo networksetup -setsocksfirewallproxystate networkservice on | off
sudo networksetup -setwebproxystate networkservice on | off


sudo networksetup -setsocksfirewallproxystate Ethernet off
sudo networksetup -setwebproxystate Ethernet off

man networksetup will reveal other proxy options (gopher, ftp, etc.)


Use "Locations" under Network Preferences.

Set up a location that has the proxy and then a location that doesn't. When you want to use the proxy, pick that location and your settings will change.


Take a look at this page at YourMacGuy about the Terminal command networksetup. Although the page dates from 2008, the command exists and works in macOS Sierra. Perhaps one of the proxy-related commands will work for you. You can always create multiple Locations in System Preferences > Network that can enable or disable the proxy. You will still need to open System Preferences, though.
