Hi I'm on OS X 10.6.6 with MacRuby 0.9 installed via RVM on a older i386 MacBookPro2,2. Check out this screenshot: http://www.delirium.ch/test/connections.png Due to the lack of templates, I've created the project in Xcode 3 and then worked with it in Xcode 4 - which worked just fine in the last beta, the GM and now the final. And it works as well for newly created XIBs, not just for the generated MainMenu.xib. Cheers, -sven
