 A universal binary contains code that can run on different architectures.
 By default, the operating system will select the architecture that most closely
 matches the processor type.
-This means that an intel architecture is selected on intel processors and a
-powerpc architecture is selected on powerpc processors.
 A 64-bit architecture is preferred over a 32-bit architecture on a 64-bit
 processor, while only 32-bit architectures can run on a 32-bit processor.

 When the most natural architecture is unavailable, the operating system will
 try to pick another architecture.
 On 64-bit processors, a 32-bit architecture is tried.
