This can probably be fixed by setting this key in the app's info.plist file: 


Under the hood, Tkinter/Tk-Cocoa uses CoreText to render text, and I understand 
this to adapt to high-res displays out of the box--as long as the proper key is 
set in the plist file. 

Only pixmaps/images require special developer handling to display properly on 
Retina displays. As IDLE does not use any such graphics, it should be fine. 

Can someone file a patch for the info.plist file, or at try editing the app's 
info.plist file and then testing on a high-res display? I do not have access to 
a Retina display machine on my system. Here are more details on how to enable 
the key and test it:
