I'm currently in a MacBook CD 2.0 Ghz with 2GB RAM (max RAM possible). I have Aperture 3 and I can handle D40x files (10 MP), slowly but bearable. I will eventually upgrade my mac. Waiting to see if a new design comes next year. But I would hate buying a camera and not being able to edit photos because of my Mac. So, anyone here with a similar Mac to mine and a D7000?
