Have you read the Window Programming Guide for Cocoa?

In essence, Apple's opinion of MDI is...

"The MDI tendency directly contradicts Mac OS X, in which windows are document-centric rather than application-centric. No parent application "main window" exists--the menubar and other interface elements, like palettes, are used to constantly indicate which application is active. Document windows are only constrained by the user's desktop size (which might span single screen or multiple monitors)."

Taken from Apple's Switch to Mac OS X developer document (see the "Mac OS X Doesn't Use MDI" section). Whilst this is quite an old document, nothing has changed in this respect.
