Hello Comp 3906,
There are going to be some of you in class this semester who are first timers on the Mac. I was a PC guy for longer then I can remember until I got my first Mac Book Pro. While there are a few differences, you’ll get over them pretty quickly and you be up to speed and fairly Mac savvy in no time! To help easy the pain, here are some resources I came across that may help.
