Welcome to Mac! Be sure to check out the instructional videos on Apple's site. They also have a discussion board that may have answers to your questions. And MR has plenty of resources and knowledgeable users if those aren't enough. Not that I'm trying to pass the buck 😛 Just letting you know there are plenty of resources available 🙂
Congrats and I also have the 2.4, you will love it!!
This is a great site for everything and anything about Macs, I am new to Mac also and this site is great for help.
