Hi everyone, I have accuired my first mac although second hand from a friend of mine i guess it will get me going before i can afford something better. The mac has been preloaded with the tiger 10.4 and runs ok, and to be honest i am after two weeks of using it more than happy to make the switch from windows, however my biggest concern is online safety, as i mainly buy stuff off the net, now i had all sorts installed on my pc mainly norton for security, and i know from my friend that Applemac as i understand supplies it's own security software in the OS and although i have had an update for itunes as yet no update for security. So,,,how safe are macs for online purchases?....and do i need any extra third party security software? Thanks all and sorry to bore you! taff.
