  Debug 10.6 Project into 10.5?
  
  Can I debug a 10.6 project into a 10.5? I have computers at school that are still 10.5 and I need to downgrade it so I can run my program on their computers.
  Thanks,,

  A:
  
  I assume you mean you want to load your Xcode project onto the school computers.
  First, are you using any 10.6 specific APIs? If so, you can't run your app on 10.5.
  Right click on your project and Get Info. Then check some things:
  
  General->Project Format: Is this an Xcode version that will be compatible with the school computer? 10.5 will be an Xcode 3.1.x system (pretty sure about this, though it could be 3.0.x)
  Build->Base SDK. Is this set to 10.5?
  
  If those look good, you should be set.
