I have a question about the Mac's firewall. I have yet to place my order for a first Mac. There are firewalls and there are firewalls. Windows XP now comes with one built in, but from what I can see (and I'm not an XP expert), the XP firewall doesn't do as much as what ZoneAlarm does. I installed ZoneAlarm on my Win2000 box, and it allows me to check outgoing traffic. If a program that I installed wants to talk to the net, a popup will warn me and ask if it's OK. Unless I know why and I want it to, I can say no, and I can tell ZA to always say no to that program. So if I bought a program from a legit company who wants to be nosy, I can tell them to kiss off. The XP firewall does not appear to guard against outgoing traffic. So I wonder about Mac's firewall. Does it do anything like what I described ZoneAlarm doing ?
