Headless permissions

[br...@dockyard.com]

When launching Chrome from the CLI if I don't use `--headless` Chrome launches without issue. But if I add `--headless` I get "Permission denied" errors.

Is there a way to ensure that headless mode has the necessary permissions? What exactly is different about headless mode that it would require permissions?

What operations are failing with Permission denied?  Loading a web page?

This is the output:

➜  MacOS ./Google\ Chrome --headless

it appears a `mkdir` command is failing. My installation of Chrome is just the normal dmg installation. I could run chown on the directory but I would have to ask all consumers of our lib to do this every time.

Could you check if the --disable-crash-reporter command line flag makes the problem go away?

I was just about to follow this up with:

I added `--crash-dumps-dir` to a path the launching process has permissions to and this resolved it. Thanks for following up!
