This guide will teach you how to set up a proxy server on macOS using SquidMan.

What's a proxy server?

A proxy server is a computer that sits between a user and the Internet, and when using a proxy, all traffic between the end user and any website they visit is channeled through the proxy server. There are a number of reasons to use a proxy server, and one common reason is to make it look like traffic is coming from the proxy server's location, not the end user's location. This can give users access to content that is restricted by location. Proxies can also provide other functionality like data encryption, caching, network optimizations, and more.

SquidMan download on macOS

We're going to use Squid as our proxy. We're actually going to install SquidMan which is a manager for the Squid proxy cache. Installing SquidMan is all you need to get started.

Click here and download the appropriate version. The SquidMan version will depend on what version of OS X you're running.

After downloading SquidMan open the dmg file and move the SquidMan application into your Applications folder.

You can open the app by using Finder to navigate to your Applications folder and clicking on the SquidMan icon.

Or you can simply type cmd + space bar, and search for squidman. The app will open up to the preferences page.
