Xcode Export Mac App without Developer Program

Question

Edit: I wrote this years ago, but to clarify (if I remember correctly), the issue was a conflict between the project-wide build settings and the build settings for the particular target. The solution is to remember when you use the project editor, you have to highlight the right entry in the projects/targets list, remember that bolded settings override the default, and the final value is determined by the most specific override. If you are stuck, select the "Levels" view at the top of the "Build Settings" tab and it will show how each setting is determined. "Levels" mode is ordered left to right in order of decreasing precedence; the leftmost column is the final value, and the rightmost is the default. See the docs for more info.
