Plug Spy is our first application which is optimised for the new Retina Mac Book.
Minco and Webbla will get Retina ready graphics with the next bigger updates.
We are expecting that Retina iMacs and an Apple Retina Cinema Display will follow later this year.
Plug Spy 1.2.8 is currently only available on our website. If you have purchased Plug Spy in the Mac App Store and would like to get the Retina version let us know. The Review process may delay the availability in the Mac App Store for some weeks.
