On some of the other OSes it is confusingly named amd64. Is it an architecture, or is it something like a Transmeta chip doing 386 dynamic binary translation via System On a Chip with modified-Minix spyware in the firmware? My Intel Macs are all dead. My PowerPC G3 and G4 Macs are all still running. I am a little bit jealous of the G5 owners on this forum especially those with 16 GB RAM.
Here are some (unused) folders on my PowerPC Mac:
/usr/include/architecture/i386
/usr/include/i386
/usr/include/libkern/i386
/usr/include/mach/i386
/usr/include/mach-o/i386
/usr/include/pexpert/i386
/usr/libexec/gcc/darwin/i386
/usr/standalone/i386
Apple was testing and running Mac OS X on Intel way before the switch to Intel.
x86 is the universally-recognized name of the architecture. Point still stands.
Maybe your G5 still runs, but so do all of my mid-2000s x86 computers, and all of them are exponentially better performers in practice than the dual-processor G5 ever was (I know what the synthetic benchmarks say).
