The text can be made Retina-friendly with a new key in the app's 
Info.plist file:

<key>NSHighResolutionCapable</key>
<true/>

CoreText provides the HiDPI hooks out of the box.

The other trick mentioned on-list, from SO, doesn't seem to work if 
you're on Lion. Bummer.

When I get the app I'm working on a bit further along, I may post a 
request for testing from someone with a Retina Mac. My interest here is 
documenting best practices for Tk apps in this brave new world, and I 
will do so.

A related technical question: my theory that the tk::mac::iconBitmap 
command is the way to go is untested, but it provides direct access to 
the NSImage API's that are in effect here. Standard Tk images do not. 
However, I noticed that TkImg at some point added support for multi-file 
TIF images in a single file--does anyone have experience with that?
