Hi guys/gals, Just noticed that my firewall was switched off. Did I miss something when I first setup my new MBP or is it like that by default? I thought I'd start a new thread as some people may not be aware of this. I've looked through some of the older threads and some mentioned the previous versions were a bit flakey but as its 2010 I thought things may have changed since. I just can't find a reason for not having a firewall configured and switched on and why its switched off by default. We've always had our firewalls switched on on all our Linux machines at work and at home so I don't understand why it shouldn't be on on an OS X unit. Can anyone enlighten me?
