A Few Questions about running on MAC OSX

I was amazed how easy it was to get my code over from the PC and running on Xcode.
I just have a few questions though.

When I close my app using the Juce “X” quit method the app quits but then OSX reports a crash error. If I close the app from the apple menu bar pull down it seams to close properly. Anyone have any idea what might be going on?

Also does anyone know a way I can get rid of the juce title bar altogether and replace it with the standard OSX carbon app window?

Does anyone know if its possable to contant a juce app inside of a .nib file window?

The whole idea of JUCE (at least one thing I like about it) is that its pixel perfect on all the supported OS.

That means it doesn’t use native window look and feel. That said I bet its possible to do what you want, I wouldn’t know how though.
