MacProxy is a program that provides system-wide network proxy support for Mac computers. It allows users to hide their IP address and surf the Internet anonymously by forwarding network settings to a proxy server. This software supports all major browsers, including Safari and Firefox, as well as applications such as Mail, iChat, FTP and Telnet. It even has the ability to connect via iPhone, turning it into a local proxy.

One of the advantages of MacProxy is its ease of setup and administration. Adding a new proxy is very easy, and users can monitor the amount of traffic going in and out of their proxy. In addition, MacProxy is very lightweight, so it does not slow down the system.

However, the downside of MacProxy is that it does not include public proxies. This means that users already need to set up a proxy server in order to take full advantage of the software.

Overall, MacProxy is an ideal tool for network administrators or Internet users who want to maintain their privacy or access sites that are usually inaccessible outside their country.
