Im the new owner of my first new Mac, A black Macbook. So like all new things, there will be some adjusting. two questions 1. In my old pc, i have a mouse with a scroll ball? in the middle of it. In which then I click on the website and can scroll down the page with just scrolling the little ball. Can I do this with an apple mouse? or even in a mac os? 2. Copy and paste, will I be able to do it as I have always done it in a pc?
