How does OS X apply this warning and what's the best way to disable it?

I'm a Web Developer and more than understand the risks of teh interwebs.

  • @nathan-g Thanks, but I think I need just a little more rep before that restriction is removed :) – PhilSwn Feb 26 '11 at 16:31
  • @nathan-g Ah, nm, I leveled up! – PhilSwn Feb 26 '11 at 16:59

Use the Terminal and this command:

defaults write com.apple.LaunchServices LSQuarantine -bool NO

That will disable warnings completely after you restart the system. To reverse it, run it again with "YES" instead of "NO".

Or you can create a custom listing of safe files with the method described here:

Custom assessment file for downloaded files
