PortAuthority makes it easy to install thousands of Unix software packages for Mac OS X. Powered by the MacPorts Unix-software management system, PortAuthority's familiar three-pane interface lets you get started doing what you want to do--finding, installing, and removing software.
To install PortAuthority, download the latest version. It can be installed anywhere on your machine. Earlier installations can be moved to the trash. The download is a 30-day demo; you can purchase a license to use the program past the 30-day trial period. Mac OS X 10.13 is the minimum supported platform. A MacPorts installation is also required; MacPorts can be downloaded from http://www.macports.org.
Registered users of our applications receive free upgrades for life, and never have to pay an upgrade fee.
