From the Synergy ReadMe:

"Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware."

Synergy is a great tool, but it's missing a GUI that would make it act like a real Mac application. We started SynergyKM to fill that void. SynergyKM is a complete package; it includes a preference pane and menubar item, along with a full copy of Synergy.

• Configuring Synergy client or server in a GUI
• Auto starting Synergy on login
• Handling multiple users and reconnecting after sleeps
• Handling multiple Synergy configurations/Locations (like Mac OS X's Network Locations)
• Automatic detection of locations using Bonjour networking (only works with Mac clients & servers for now)
• Menubar item with the Synergy status & locations for quick access

Version 1.0b7, released Sept 6, 2009:

• Snow Leopard and 64-bit support
• Now using Synergy 1.3.1
• New hi-res icons and graphics
• Installer is now self-contained

Mac OS X 10.5 or 10.6

Mac OS X 10.2 - 10.4 users: please use an older version of SynergyKM found on the website

Use the supplied installer.
