I just got a new Macbook (white unibody mid 2010) with stock specs. I ran iMovie the other day, throwing a video together, and it crashed on my a couple of times. Granted I was multitasking with safari also being open, but is that normal? I didn't think that would tax that system very much. I was considering upgrading the RAM from 2GB to 4GB and was wondering what a good price on the RAM would be around. Where's a good place to get it? I know about Crucial, but it says about the same price as Apple was going to charge me to upgrade. Does black friday tend to bring RAM sales about? If so, from where? Thanks!
