I'm got my iBook yesterday, and am still in the process of wiping my drool off the case. When I reformatted my PC's harddrive and installed Windows, the first thing I did was install ZoneAlarm. Does something similar exist for MacOS? I saw a firewall option in the 'Sharing' control panel. However, it looks like the Windows XP firewall which I always kept disabled because it was difficult to configure and only checked incoming traffic. I need something bidirectional that stays out of the way, yet pops up and asks me if I want to allow or disallow traffic. Can someone point me in the right direction? Thanks.
