Why [Debug] button is replace by a [Morph] button in Xcode?

Question

In Xcode (3.2.4), View > Layout > Show Page Control.

In my old MacBook's Xcode, the Page Control shows [Project] and [Debug] buttons. In my new MacBook, the Page Control shows [Project] and [Morph] buttons.

How can I get the old [Debug] button back and get rid of the [Morph] button? Thanks!

Answer 1

Close out any open projects. XCode Preferences -> General tab -> Layout -> All-In-One instead of Default and you will have your [Debug] button back.

Cheers.
