Disable file extension change warning in Mac OS X

When you try to change a filename and you change the file extension, you get a warning by default from Mac OS X.

To disable this, execute this command in your terminal:

defaults write com.apple.finder FXEnableExtensionChangeWarning -bool false

 And after that you need to restart your Finder

killall Finder

 Now open up a new finder window and you shouldn’t get anymore warning from now on.
