Reply to First time with S4 and MBP=D

Hi again peeps, i used S4 for about 2 months now with my win computer, today i got a MBP But i never used a Mac before, but i got very good computer skills when it comes to win pc's.

So my question is, since i got my first gig with it tomorrow, what should i do to preper for tomorrow? Turn of wifi and BT ofcourse but is there anything else?
