From the mailing list:
"node-webkit requires at least OS X 10.7, 10.6 will also work after
fixing this bug:
Also this, regarding minimum spec for node-webkit mac export:
"Currently we require 10.7.x, after fixing this bug we will only
require 10.6.x, and Chrome requires 10.6 as minimum which means we
would never support 10.4.x."
For osx 10.6, one must build node-webkit on it's own; a prebuild package can be found here:
Not sure is this the issue here, but i haven't seen any info on the osx version this bug occurs on.
Be nice until it's time to not be nice
