问题
I am building a Mac app, but the "Build and Archive" menu item is disabled. I am running Xcode 3.2.4 and OS X 10.6.5. Any suggestions?

Download and install the "Application Tools" package fixed it for me.
Links to the Application Tools download can be found on the index page for the Mac developer program.
