CS6 does not support the ultra-high resolution of the Retina displays. The necessary code to do that was part of making CC a 64-bit program.
Are you joking? I paid $ 2000 for something what does not work well ?
How is it possible that they don't support Retina...
As already pointed out, Adobe re-wrote the code for InDesign CC. It was impossible to add that to any version prior.
