i lost here, , not sure else do. help much appreciated.

update:

thanks this question, resolved downloading postgres.app mac. works great now.

this quite easy think because if update mac process running postmaster.pid file missing /usr/local/var/postgres/ here. need start process postgres create postmaster.pid.

if progress running -

stop manually:

pg_ctl -d /usr/local/var/postgres stop -s -m fast

start manually:

pg_ctl -d /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

now working...
