Is the firewall enabled in Mac OS X by default, or not?


I just bought a new MacBook, as I'm stepping down from owning a Pro and moving to a MacBook/iMac setup (more on that later), and I noticed something a little disconcerting: after going through the generic setup out of the box, Mac OS X's firewall was not enabled by default. I didn't fiddle with any settings during the initial boot and setup (besides entering a password for my wifi network and my .Mac credentials - about the only settings you can fiddle with), and I spotted this strange quirk in the Sharing Preference Pane when going to name my machine before the initial .Mac sync.

What gives? Is Mac OS X 10.4's firewall enabled by default or not? I honestly don't remember which exact version of 10.4 this MacBook shipped with (I ran Software Update immediately on startup and only caught this firewall quirk after the restart), and I'm certainly not some certified, 6-figure security expert - I'm only reporting what I saw with this initial setup.

So does anyone know what's going on? Discussions about Mac OS X's (and 10.4 specifically) inherent security often cite the firewall being turned on by default - though that clearly wasn't the case with this machine. What say you, TUAW readers?

Fix for .Mac sync errors with Mail and random signatures

I recently set Mail on both of my Macs to chose a random signature. From time to time during a .Mac sync, I'll receive an obnoxious sync error claiming that a 'default' signature on one Mac is conflicting with the other. No matter which signature I choose to resolve the conflict, the sync process will lock into a loop, repeatedly offering me a sync error with new choices on either end for resolving the conflict. Obviously, this has lead to an increase of Advil in my regular diet.

If you're nodding your head right now, you'll be happy to know we all can cut back on the pain killers. For the first time in a while, I actually received a helpful message from Apple's email support that said something more than "try rebooting." Turns out that, unfortunately, if you enable Mail's random signature feature on one Mac, Mail can't be running on other registered Macs for the first sync after this new feature. I replied to the support rep's email to find out what is up with such an odd quirk, but I didn't receive a very useful answer.

Nevertheless, after getting back to square one by resetting my signature data on both Macs, I can verify that this fix works. Hopefully, this issue is on the list of updates coming in 10.4.4.
