I'm having issues opening up XCode 4 beta 4. It gives me an internal logic error. I'm running OSX Lion. Here's the reason why I need the XCode 4 beta 4: My iOS is on beta 4 and the previous version of Xcode(working) wasn't seeing the iPad 2 I have. So, I needed to upgrade to the latest version of XCode. I'm on a MacBook Classic White plasticy (2008 model). Please help! Sorry for the English!
