Hi! I have a quite old Mac iBook (2001) and a bit younger eMac (2003). Both running fine (Mac OS X 10.3.9). I bought many years ago Norton Systemworks 2.0 and used that until that went out of the date. Since then I have used only shareware or even free utilies (such as Optimizer which I have found to be the best, at least for me). I went to have a look on Symantec web site and found out that it is impossible to upgrade Systemworks 2.0 to the newest version and they (all their stuff actually) are really quite expensive (from about 80 euros up to 130 euros or so). So, my question is: Does Mac OS X really need their stuff (Systemworks, Firewalls, Internet Security etc.)? At least so far I have managed without them, but who knows what can happen in the future. All answers will be much appreciated! Thanks folks!
