I found situation with 64 bit on Snow Leopard as quite confusing
3. whatever kernel you booted from arch command always return i386
4. uname -m return x86_64 if you booted from 64 bit kernel,
otherwise it returns i386
5. uname -p always returns i386
Arch and uname -p both return the processor family type, i386. (as
opposed to ppc or arm.) I think the rationale was that too many
scripts depend upon this behavior.
uname -m tells you which slice of xnu you booted from, i. e. x86_64
for the 64 bit kernel, i386 for the 32 bit kernel.
It's unfortunate that the phrase i386 has two meanings.
