Hello Friends, I'm paranoid about someone accessing and monitoring my activity on my macbook (because they told me they can do it). I've activated the built-in firewall that comes with the mac and I have intego virus barrier x5 installed. But I'm not sure if my firewall is working properly. Is there a way to know if someone has access to my computer? How can I make SURE nobody can hack into my macbook? Thanks, James
