Retinizer is a small app I wrote that allows apps that aren’t retina ready and are displayed pixelated at 1x to display their UI widgets at 2x. That way, only their custom images will look bad and not the whole app.
I just used it to force Word 2008 to show retina text in Word documents instead of pixelated crap — it worked. What a simple little app that works well (note not to use it on Adobe apps). I wish I could pay this guy for the app.
