It was '95 when I got my first Power Mac. Great 'puter, too expensive. Went to PC. Now, I am doing photography professionally and just ordered a MacPro as my older Vaio PC is a waste for photoshop and Nikon Capture NX. I need the speed and dedication. So, a couple questions. As I said, it's been a while since my last Mac. What can I expect for CS3 and Capture NX on this new Mac? Just asking this in a round about way. Basically, I am asking what to be careful of and am also asking if there is anything I need to be more careful of than others in a general way. I am not going to employ windows on this as the Vaio PC is still good. Do I need anti-virus or anti-spyware while using the Mac interface? Sorry to be so general, just am looking for some experienced input for a new user of Mac. any advice will be welcomed. Thanks.
