hi,
can google see it? I can not create a new account. what do I need to do for the new account? pls help me 
Nobody knows?
I am almost certain they can not see it especially if you're using Firefox. Never use Google Chrome to do things on Google. They see too much with Google Chrome. Use Safari, or Opera, or Firefox.
dont be so paranoid you can make 10 accs of the same system you need to "switch up your system" change screen res change browser version
Technically it's not possible (barring a few extremely dodgy and possibly illegal in some juristictions hacks) to pull a MAC address from a client as a web server.
Given it's Google, though, I would strongly recommend using Firefox not Chrome, just to be sure. It's unlikely they've set Chrome up to pull MAC addresses, not least because of the aforementioned legal issues, but you never know.
