It appears that homebrew used to have -march=core2 -msse4 in bottle builds but dropped the -msse4.

test build with -march=core2 -mtune=nehalem going
if I'm reading correctly, nothing older than sandybridge is supported by apple on a software side, so can bump the to -march=sandybridge

We now depend on sandybridge. mtune was not sufficient
