I recently had my MBP replaced due to screen flickering. The new hardware is exactly the same as the previous hardware (3.06, 4GB, 7200RPM 500GB). My question is - is it ok just to swap the hard drive from the old machine and put it into the new machine? I'm not sure how things like color profiles, permissions will be affected. I know it will work, but not sure if it is recommended... Thoughts?
