Hey, I'm a new Mac user, and I was loving my mac a lot. My last computer was 4 years old with 512MB or ram and 2.8GHZ celeron processor. I bought a new Alu 20" iMac with 2GHZ duo + 2GB of ram. For the first day it was really fast, but after I started using it for about a week it seems like it's slowing down. I only have a few programs installed (Photoshop, After Effects, Parallels). It takes like 5 seconds to open the internet, about the same as my 4 year old PC. But that's not the biggest problem I'm having, It randomly slows down and thinks. I open photoshop let's say and start using it, then go to my desktop to load preferences and it stops and thinks for a few seconds then finally opens. Plus my mac has frozen twice in the last two days. What's going on? Is it parallels? Does having parallels installed slow it down even though it's not running? (Just something small, when I got to iStats it shows about 1.5GB of ram "Inactive" instead of "Free"). And just another question. I'm thinking of getting the student version of 3Ds Max from my school, and I'm wondering how well that will run on Parallels with Vista. And if it wont, will it run better if it was XP. OR Should I use bootcamp?
