Hey everyone. Quick question for you all. (I have read the forums but can't find an answer to the problem I am having) I am using a 2.2ghz Macbook Pro with the nvidia 8600 graphics card. I have 4gb of ram and a 200gb 7200rpm seagate hdd. What I want to know is, why is my Aperture painfully sluggish. I understand most computers can get bogged down with large RAW files but it's just painful now when I move sliders and get the spinning beachball for a moment or two while it has a think to itself. My library on the Mac itself is only 26gb. I store all my Aperture projects that are unused on a external hard drive. Even if I run my library off the external hard drive it's still slow as hell. So... Wondering if you guys could possibly point me in the right direction. Aperture shouldn't be too much of a problem for my Mac. I remember Aperture 2 working far better on my old Core Duo MBP with 2gb of ram. Thanks!
