It seems the "default" download of the whole SDK is still Carbon.  No there's no way to tell from the download name on that one.  I didn't try to download that 584MiB monster to see if there's any other indication on the disk image, or verify that it is Carbon.

-> Qt: Framework only, for Mac

There you can download the Cocoa build.  And it's much smaller ;)

I guess Nokia assumes people want the whole development environment.  If you do need the IDE, you should be able to install the Cocoa package on top of the "SDK", though I'm not positive that will not mess up something in the IDE.
