The first incarnation of Synergy was CosmoSynergy, created by Richard Lee and Adam Feder then at Cosmo Software, Inc. (Silicon Valley), a subsidiary of SGI (Silicon Graphics, Inc.), at the end of 1996. They wrote it, and Chris Schoeneman contributed, to solve a problem: most of the engineers in Cosmo Software had both an Irix and a Windows box on their desks and switchboxes were expensive and annoying. CosmoSynergy was a great success but Cosmo Software declined to productize it and the company was later closed. Synergy is a from-scratch reimplementation of CosmoSynergy. It provides most of the features of the original and adds a few improvements.
In 1992, at MacHack, Eric Hayes partnered with a (future) co-worker to write what they called NetMouse, a very rough predecessor to Synergy.
The Synergy+ fork project was started in 2009 by Sorin Sbârnea for the purpose of fixing bugs inherited from the original version. As of 6 June 2010, Synergy had not been updated for 4 years (since 2 April 2006). Though the Synergy project had never been officially abandoned, public discussion speculated to that end. Chris Schoeneman (the original author and founder of Synergy) said that instead of supporting a 1.3.x team, he would like to release version 2.0 of Synergy, and in 27 Aug 2008 noted that he had made progress.
Nick Bolton joined the Synergy+ project in 2009 and lead the re-integration of Synergy+ back into the original Synergy project. Nick is now the project leader and primary developer responsible for all development (bug fixes, new features, project management, etc).
