Hello guys, I've just purchased a macbookpro and made the switch from windows. When it comes to Macs, I'm completely a noob and I don't know a thing. Is there any special hot keys that you guys can share? For example in windows we have the alt+ctrl+delete button to get your task manager etc....or special services like disk defragmenter to defrag your drive. Anything will help! thanks a lot! Justin PS: my macbook pro is coming!!!!
