I am developing a WebGL driven application and I want to launch chrome like this from the command line:
open -a Google\\ Chrome --args --disable-web-security
Why not just run a webserver? Open a terminal and type
cd folder_with_html_and_assets python -m SimpleHTTPServer
Now in your browser to go http://localhost:8000 When your done go to the terminal and press Ctrl-C
http://localhost:8000
That seems much better than disabling your security and risking getting pwnd.
