Mac OS X supports 4 architectures. PPC 32 bit. PPC 64 bit (G5). Intel  
X86 32 bit. And
X86 64 bit (The new pro towers are Intel 64 bit processors and have up  
to 4 dual core

At installation, the installer queries the hardware to find out which  
processor is present
and then installs the correct files for that architecture.
