    Its nice to find a Mac-related blog with a security section (I found you via DP).

    Too many people think that the Mac and OSX/Snow Leopard are inherently totally secure but that, alas, is simply not true.

    Wow, great effort! OS X is probably the most secure OS out there (after Linux). And I think that’s because inbuilt features such as firewall. Windows came out with it only recently. OS X had it all along.
