With every launch on mac os, it causes mac os to ask the following question

"Do you want to the application Chromium.app to accept incoming network connections?"

Steps to reproduce

• Puppeteer version: 1.18.1
• Platform / OS version: Mac OS Sierra 10.12.4
• Node.js version:v11.2.0

What steps will reproduce the problem?

const browser = await puppeteer.launch({ headless: false })
and visit any url...

What is the expected result?

Chromium window appear with the site content

What happens instead?

Chromium window appear with the site content
And the Mac OS alert pop ups asking "Do you want to the application Chromium.app to accept incoming network connections?"

No matter what you do with the Mac OS Firewall setting it keeps asking it again and again and again.
