Score one for the Mac

This morning, I was expecting a Skype call. Ten minutes before, I started up my PC (we had an outage overnight). All was fine except Skype didn’t recognize the skype name of the person who was going to call me. Odd. So, I downloaded and installed Skype on the Mac, and it worked immediately.

On the one hand, this was probably a firewall (ZoneAlarm Pro) issue on my PC. On the other hand, I don’t seem to have firewall problems on my Mac. I don’t even know if I have a firewall on my Mac, which is how it should be. [Tags: ]


By coincidence, in order to log onto the Harvard network, I’ve had to turn on my firewall, and thus have discovered where it lives on the Mac.

  1. OS X Firewall: System Preferences > Sharing > Firewall Tab. One click to start or stop, check boxes for the most common ports to open/close, and easy custom port opening.

    do you really mean that? I’m all for it Just Working, but that doesn’t include having no idea how exposed your computer is!

  3. Fair enough. Let me amend: The firewall should (ideally) work with a minimum of user interaction. I spend a lot of time tuning my Zone Alarm firewall on my PC. It defaults to constantly interrupting with notices and warnings.

    I’m all for getting the defaults right.
