Hoorah! You can download it!
SynergizerOSX-1.zip Synergizer for OSX
SynergizerXP.zip Synergizer for Windows XP
You need to know the IP address of your Synergy. The username and password default to the Synergy defaults, though you can modify them in the preferences. You also need to have Quicktime installed. Should work on any Synergy MD or MD-X, though I’ve only tested it on my 2MD.
Why would you want to use it? Well, first off, it’s your only option on the Mac. Secondly, it allows you to upload any image file format (jpeg, gif, PSD, whatever), and it’ll take care of getting it into the right format for the Synergy. Drag and drop, easy peasy, hoorah!
Edit: Apparently the Synergy doesn’t like ampersands and whatnot. I’ll fix that in the next release, for now just name your files appropriately.
