How do I use modern coreutils on Mac?

How do I get modern coreutils on mac? --- I ran into this problem using csplit: foo.txt:

foo
1
foo
2
foo
3

$: csplit foo '^foo$' '{*}'
# error

Double checking the manpage, man csplit, csplit on Mac is the FreeBSD version and does not offer the '{*}' option. In fact, I must provide the exact number of splits ahead of time. This will either trigger a czplit re-implementation by me, or maybe I can get GNU coreutils on mac. Is there a way?
