Unfortunately, I have no idea of what needs to be done. I think either XCode or NSApplicationMain() must do the right magic to make applications work in Retina-display mode, and somehow we have to recreate that. Essentially all OS/Cocoa interaction for `racket/gui' is implemented dynamically via the FFI, as opposed to static configuration that XCode normally installs for a GUI application. Also, we can't call NSApplicationMain(), because it takes over the process. The `racket/gui' startup for Cocoa is mostly here: collects/mred/private/wx/cocoa/queue.rkt For example, you'll see the call to TransformProcessType() that can turn a console-started `racket' process into a GUI process. The "Working without a nib" series of blog posts provides a flavor of what `racket/gui' has to do: http://lapcatsoftware.com/blog/2007/05/16/working-without-a-nib-part-1/ That was written long before Retina displays, though, and I haven't run across any updates that look relevant. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
