I don't get this? I'm hardly ever doing anything intensive on my machine, and on more than one occasion Safari will lock up and usually quit, Finder has locked up a few times. I've had Photoshop lock up when doing the simplest of things. I usually only have iTunes, Safari and Mail open, so why would it react this way? My 2010 I used to have never did this. It's happened over the last month and a bit I reckon. I don't run Windows, and I haven't even pushed it to it's full potential yet. I don't want to because by the looks of it it won't cope. What should I do?
