File Watcher / LESS/ Nothing happens

i'm using Mac.

All are lastest versions.

installed node with 'brew install node'

installed less with 'npm install less -g'

added *.less file in WebStorm 6.

popup shows.

added almost default settings for less except 'Program: /usr/local/bin/lessc'

oops, error, lessc not found,

fixed path to '/usr/local/share/npm/bin/lessc'

*.less files automatically saved, but no *.css.

hm...

tried this, tried that, no difference, nothing happens.

restarted WebStorm.

Oh, It works.
