Comment:

 This can in fact be fixed (mostly, not icons and stuff) on the macports
 side. I did it on my wifes macbook pro after a bunch of reading on digia's
 webpage. The problem is that the .app Info.plist must contain the
 following lines under the <dict> tag:

         <key>NSPrincipalClass</key>

         <string>NSApplication</string>

         <key>NSHighResolutionCapable</key>

         <true/>

 It is possible to add these in an existing .app dir and then make a copy
 (triggering mac os to do some caching I'm guessing) in order to fix these.
 I fixed it for spyder by opening the
 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/Info.plist,
 adding the lintes

 like so (a little context included):

 <dict>(context)

         <key>NSPrincipalClass</key>

         <string>NSApplication</string>

         <key>NSHighResolutionCapable</key>

        <true/>

        <key>CFBundleDevelopmentRegion</key>(context)


 making a copy (in the finder by dragging, don't know if cp -r will work)
 and then renaming the original to python.app to python.app.old in the
 finder and renaming the copy to python.app . Starting spyder (a pyqt
 application) from the terminal now launches it in high-res.

 So just fix all the Info.plist's and this will fix most things...
