Is there a way to determine if an App is running on Intel or PPC

Depending on what you're trying to do, you can go at least a couple
routes at build time.
If you only care about endianness:
#ifdef __BIG_ENDIAN__
#ifdef __LITTLE_ENDIAN__
If you care about the actual architecture:
#ifdef __ppc__ // 32-bit PPC
#ifdef __ppc64__ // 64-bit PPC
#ifdef __i386__ // 32-bit Intel
#ifdef __x86_64__ // 64-bit Intel
There are also parallel ones defined in /usr/include/
TargetConditionals.h:
#if TARGET_RT_LITTLE_ENDIAN
#if TARGET_RT_BIG_ENDIAN
#if TARGET_CPU_PPC
#if TARGET_CPU_PPC64
#if TARGET_CPU_X86
#if TARGET_CPU_X86_64
