Crash

I was trying to render a scene ( 01.blend from the “apple” folder) from Big Buck Bunny so I could learn how to properly set up lighting but Blender crashes everytime I set the size of the render higher than 15%. I’m guessing it’s because my mac book pro is 3 years old and only has 2 Gigs of ram.

What kind of computer do I need to render a scene like that at a minimum? Or, would I need a render farm?
