ShapeShifter is a revolutionary new product that lets you change the overall appearance of your Mac using 'themes'. We're not talking about just desktop backgrounds and icons here, we're talking about everything - the look of windows, menus, apps, buttons, absolutely everything. You don't wear the same clothes every day, your house doesn't look exactly like your neighbor's - why should the computing interface you use every day be any different. You personalize your physical workspace to suit your tastes and whims, so why not your Mac? With ShapeShifter, you can:
  • Change the overall appearance of your operating system safely, quickly, and reliably
  • Tweak existing themes to create the one that's perfect for you
  • Experience things that haven't been possible with Mac themes before
  • Quickly preview themes without actually applying them
  • Use Jaguar or Panther themes in Tiger effortlessly
  • User specific theme and icon set installations
  • Add and remove themes effortlessly

Where To Find More Themes:
In addition to the themes that are available through ShapeShifter's "Download" tab, many others are available on the internet. Websites where themes can be found include:
