If you are on a Mac Retina display and using Indigo, you may have noticed it's not as crisp as it could be. This is due to a technology limitation with Silverlight rendering on Retina displays.
However, the good news is that there is a workaround for it. In your Applications, right-click on Indigo Studio and click Get Info to bring up the app info. Under General, check the "Open in Low Resolution" box as shown in the image.
That's it. Next time you open, it should show, more or less, how it does on non-retina displays.
