Yesterday, I bought Rayman Origins from the Mac App Store. It appears in the Applications folder stack on my dock as "Rayman® Origins"
That small registered symbol looks pixelated and ugly on my non-retina screen. So I opened my applications folder in Finder in order to rename the application.
If I rename the app to "Rayman Origins1", it appears fine. Likewise, if I rename it to "RaymanOrigins", the name changes as I would expect. However, I cannot seem to rename the app simply "Rayman Origins". Although Finder lets me type in the name, as soon as I hit enter, it snaps back to "Rayman® Origins" with a registered symbol.
