Hi everyone, I've been thinking seriously in getting a Mac and finally change the other OS that I have, but before I've got some questions regarding the computer. I use a lot the computer for downloading/uploading music, sometimes I get programs through the net and so on, will I need an anti-virus?I know Apple is virus-free but downloading so many things and stuff do I have a chance to infect it? Been recently to an Apple store and they showed me an anti-virus.... i suppose it's regarding the windows option... Another thing is the fact that the Macbook doesn't have a very high graffic...(64MB) does this really affect the computer in any aspect?appart from playing to videogames... I've heard they gonna replace once again the Macbooks by a range of new ones with a possible change of the graffic...and something else...is that possible? Knowing that they're kinda new,just a couple of months since the latest renew... Thank You!
