FreePPP is a Point to Point Protocol (PPP) implementation for computers running Mac OS prior to Mac OS X. FreePPP was widely considered the first working and most stable version of PPP for Apple Macintosh and led many PPP internet service providers to support Macintosh users for the first time.
Besides the overall stability, usability was a large factor in the popularity of this implementation. A menu bar icon was introduced that gave users easy access to common tasks such as dialing and disconnecting. Modems were "auto-detected", keeping users from having to find and configure an init string for their modem (a common stumbling block for users). FreePPP was installed by a "lite" version of the commercial Internet Setup Monkey product, whose producer Rockstar Studios was a primary contributor to FreePPP. The installer included cartoon images of a monkey installing software on the computer.
