i bought a macbook a couple months ago and it's now running slow as hell. i use a wireless internet connection; I've asked my roommates and their internet is running normally. it's gotten to where i can't watch youtube videos because they'd take over an hour to load up. in all seriousness, i go to porn websites a lot and i wonder if it's putting some kind of crap on this thing that's slowing it down. also no joke: i'm considering buying a cheap second computer to use exclusively for porn and save this one from dying altogether. I've read dozens of posts on other threads in which people argue that there isn't any spyware and/or viruses for macs, and then argue endlessly about the definition of "spyware" and "virus," etc. I don't care what it's called, and I don't care what it does other than slow my computer down. all I know is i have a brand new $1500 macbook with 2Gs of RAM, it takes 10 minutes just to check my email, much less do anything more complicated, and I want it fixed. what can i do?
